The influences of some important operating parameters, which are the initial pH, the concentration of potassium ferrate(VI) (K 2 FeO 4) and the RO 16 dye, and ultrasonic density (for only the sono-ferrate(VI) method), on the color removal have −1 been investigated. The optimum conditions have been determined as pH = 7 and [K 2 FeO 4 ] = 50 mg L for the −1 −1 individual ferrate(VI) oxidation method and pH = 7 and [K 2 FeO 4 ] = 50 mg L by direct sonication at 0.50 W mL ultrasonic density and 20 kHz fixed frequency for the sono-ferrate(VI) method. The color removal efficiencies were 85% by ferrate(VI) method and 91% by sono-ferrate(VI) method. Kinetic studies were also performed for the decolorization of RO 16 under the optimized conditions at room temperature. It was seen that the oxidative decolorization of RO 16 via the sono-ferrate(VI) method happened more rapidly because of the production of OH • radical through sonication compared to the individual ferrate(VI) method. -

Manufacturing of Potassium Permanganate Kmno4 This Is the Most Important and Well Known Salt of Permanganic Acid
Manufacturing of Potassium Permanganate KMnO4 This is the most important and well known salt of permanganic acid. It is prepared from the pyrolusite ore. It is prepared by fusing pyrolusite ore either with KOH or K2CO3 in presence of atmospheric oxygen or any other oxidising agent such as KNO3. The mass turns green with the formation of potassium manganate, K2MnO4. 2MnO2 + 4KOH + O2 →2K2MnO4 + 2H2O 2MnO2 + 2K2CO3 + O2 →2K2MnO4 + 2CO2 The fused mass is extracted with water. The solution is now treated with a current of chlorine or ozone or carbon dioxide to convert manganate into permanganate. 2K2MnO4 + Cl2 → 2KMnO4 + 2KCl 2K2MnO4 + H2O + O3 → 2KMnO4 + 2KOH + O2 3K2MnO4 + 2CO2 → 2KMnO4 + MnO2 + 2K2CO3 Now-a-days, the conversion is done electrolytically. It is electrolysed between iron cathode and nickel anode. Dilute alkali solution is taken in the cathodic compartment and potassium manganate solution is taken in the anodic compartment. Both the compartments are separated by a diaphragm. On passing current, the oxygen evolved at anode oxidises manganate into permanganate. At anode: 2K2MnO4 + H2O + O → 2KMnO4 + 2KOH 2- - - MnO4 → MnO4 + e + - At cathode: 2H + 2e → H2 Properties: It is purple coloured crystalline compound. It is fairly soluble in water. When heated alone or with an alkali, it decomposes evolving oxygen. 2KMnO4 → K2MnO4 + MnO2 + O2 4KMnO4 + 4KOH → 4K2MnO4 + 2H2O + O2 On treatment with conc. H2SO4, it forms manganese heptoxide via permanganyl sulphate which decomposes explosively on heating. 2KMnO4+3H2SO4 → 2KHSO4 + (MnO3)2SO4 + 2H2O (MnO3)2SO4 + H2O → Mn2O7 + H2SO4 Mn2O7 → 2MnO2 + 3/2O2 Potassium permanganate is a powerful oxidising agent. A mixture of sulphur, charcoal and KMnO4 forms an explosive powder. -
Experiment: Determination of Manganese in Steel
p.1 of 4 Chemistry 201 – Winter 2007 Experiment: Determination of Manganese in Steel Manganese (Mn) in steel may be determined upon dissolution as manganese (VII) after oxidation from the manganese oxidation state (II). This procedure calls for three oxidizing agents. Manganese (VII) may be determined spectrophotometrically. During dissolution of the sample with dilute nitric acid to form iron (II) and manganese (II), nitrogen oxide gases are formed. These must be removed, partially by boiling, and the rest with ammonium peroxydisulfate which also removes carbon or other organic matter present. The nitrogen oxides may react with periodic acid which is used to convert manganese to the (VII) oxidation state. Excess peroxydisulfate is decomposed by boiling. The equations are: - + 2+ 3 Mn + 2 NO3 + 8H ---> 3 Mn + 2 NO (g) + 4H2O 2- - 2- + 2 NO2 (g) + S2O8 + 2 H2O ---> 2 NO3 + 2 SO4 + 4 H 2- 2- + 2 S2O8 + 2 H2O + heat ---> 4 SO4 + O2 + 4 H 2+ - - + - 2 Mn + 5 IO4 + 3 H2O ---> 2 MnO4 + 6 H + 5 IO3 NO(colorless gas) + 1/2 O2 (g) <---> NO2 (brown gas) Note: Peroxydisulfate has the required oxidizing potential to change the oxidation state of manganese from (II) to (IV), but the reaction is too slow. Silver could be employed catalytically but the results are too erratic. Periodate oxidizes the manganese to the (VII) state quantitatively and rapidly at the boiling point, and it is advisable to add the sparingly soluble periodate salt in several portions to maintain an excess and to allow for some decomposition of the latter salt at the elevated temperatures. -

PERMANGANATE OXIDATIONS in NON-AQUEOUS SOLVENTS* By
PERMANGANATE OXIDATIONS IN NON-AQUEOUS SOLVENTS* I. OXIDATION BY TRKPHENYLMETHYLARSONIUM PERMANGANATE By N. A. GIBSON^ and J. W. HOSKING? Quaternary arsonium cations have been widely used in analysis,l mainly in the formation, with anionic complexes, of ion-association compounds which are soluble in aprotic solvents.2 The triphenylmethylarsonium cation has been used to form ion-association compounds with anionic complexes of a number of metals3-' and has also been used to form ion-association compounds with the ~ermanganate,~di- chromate,g and triiodidelo ions. The tetraphenyIarsonium cation has been used to extract the permanganate ion into non-aqueous solvents.llJ2 The permanganate ion can be extracted into non-polar solvents from acid aqueous solutions containing tributylphosphate. The triphenylarsine oxide permanganic acid adduct is soluble in chloroform and nitrobenzene.13 Triphenylmethplarsonium permanganate has been isolateds and is soluble in aprotic polar solvents. It is very soluble in chloroform and nitrobenzene (saturated solutions are approximately l~ and 0.8~respectively) and is sufficiently stable in these solvents to make possible a study of oxidizing properties of the permanganate ion in non-aqueous media. While triphenylmethylarsonium dichromate has no oxidizing properties in non- aqueous solvents,ls the corresponding permanganate behaves like permanganate ion in neutral solution, being reduced in the presence of a suitable reductant to insoluble manganese dioxide. Preliminary investigation of the oxidizing properties of the permanganate ion in chloroform showed that propan-2-01 was oxidized quantitatively to acetone. The results of a typical reaction are shown in Table 1. Kinetics of this reaction and the oxidizing properties with regard to other functional groups will be reported later. -

In Situ Chemical Oxidation of Creosote/Coal Tar Residuals: Experimental and Numerical Investigation
In situ Chemical Oxidation of Creosote/Coal Tar Residuals: Experimental and Numerical Investigation by Steven Philip Forsey A thesis presented to the University of Waterloo in fulfillment of the thesis requirement of the degree of Doctor of Philosophy in Earth Sciences Waterloo, Ontario, Canada, 2004 ©Steven Philip Forsey 2004 I herby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final version, as accepted by my examiners. I understand that my thesis may be made electronically available to the public Steven Forsey ii Abstract Coal tar, coal tar creosote and oily wastes are often present as subsurface contaminants that may migrate below the water table, leaving a widely distributed residual source of contaminants leaching to the ground water. In situ chemical oxidation is a potentially viable technology for the remediation of aquifers contaminated with creosote and coal tars. The oxidant of choice would be flushed through the contaminated area to oxidize aqueous contaminants and enhance the mass transfer of contaminants from the oil phase. A series of batch and column experiments were performed to assess the ability of a chemical oxidizing reagent to oxidize creosote compounds and to increase mass transfer rates. Results from the column experiments were then simulated using a reactive transport model that considered 12 different creosote compounds undergoing dissolution, oxidation and advective-dispersive transport. Three strong chemical oxidizing reagents, Fenton’s Reagent, potassium persulfate with ferrous ions, and potassium permanganate were tested with batch experiments to determine their reactivity towards creosote compounds. All three reagents successfully decomposed aqueous creosote compounds and were able to reduce the mass of the monitored creosote compounds within the oil phase. -
