Preparing to Manufacture Hydrogen Peroxide
PREPARING TO MANUFACTURE HYDROGEN PEROXIDE Part of the Hydrogen Peroxide Propulsion Guide The early laboratory preparation of hydrogen peroxide was based on the technique that Thenard used during the initial preparation of hydrogen peroxide. In this technique, barium nitrate, purified by recrystallization, was decomposed by heating in air in a porcelain retort. The resulting oxide was further oxidized by heating in a stream of oxygen to a dull red heat. The barium peroxide which formed was then dampened, ground, and dissolved in hydrochloric acid (nitric acid was used in Thenard’s initial experiments). A slight excess of sulfuric acid was then added to precipitate barium sulfate and regenerate hydrochloric acid. The procedure of barium peroxide solution and sulfate precipitation was repeated several times in the same solution to increase the peroxide concentration (concentrations of up to 33 percent by weight hydrogen peroxide could be achieved in this manner). The concentrated solution containing water, hydrogen peroxide, and hydrochloric acid, along with accumulated impurities, was cooled with ice and saturated with barium peroxide; iron and manganese impurities in the solution were then precipitated out as phosphates. The hydrochloric acid was removed by the addition of silver sulfate and the sulfate ion was removed by the subsequent addition of barium oxide. Further concentration was accomplished by vacuum distillation until “no further density increase occurs.” Thenard reported that 100 w/o hydrogen peroxide (on the basis of density data and the measurement of the volume of oxygen released) could be obtained by this technique. The first record of commercial production of hydrogen peroxide appeared in the 1865 to 1875 period. -
Acrylamide Polymerization — a Practical Approach
electrophoresis tech note 1156 Acrylamide Polymerization — A Practical Approach Paul Menter, Bio-Rad Laboratories, 2000 Alfred Nobel Drive, Polyacrylamide Gel Polymerization Hercules, CA 94547 USA AcrylamideBis Polyacrylamide Introduction The unparalleled resolution and flexibility possible with CH2 CH + CH2 CH CH2 CH CH2 CH CH2 CH polyacrylamide gel electrophoresis (PAGE) has led to its CO CO CO CO CO widespread use for the separation of proteins and nucleic NH2 NH NH2 NH2 NH acids. Gel porosity can be varied over a wide range to meet CH2 CH2 specific separation requirements. Electrophoresis gels and NH NH NH NH buffers can be chosen to provide separation on the basis of CO 2 2 CO CO C O charge, size, or a combination of charge and size. CH2 CH CH2 CH CH2 CH CH2 CH The key to mastering this powerful technique lies in the polymerization process itself. By understanding the important Purity of Gel-Forming Reagents parameters, and following a few simple guidelines, the novice Acrylamide can become proficient and the experienced user can optimize Gel-forming reagents include the monomers, acrylamide and bis, separations even further. as well as the initiators, usually ammonium persulfate and TEMED or, occasionally, riboflavin and TEMED. On a molar This bulletin takes a practical approach to the preparation of basis, acrylamide is by far the most abundant component in the polyacrylamide gels. Its purpose is to provide the information monomer solution. As a result, acrylamide may be the primary required to achieve reproducible, controllable polymerization. source of interfering contaminants (Dirksen and Chrambach For those users interested only in the “bare essentials,” the 1972). -

Anipsitakis Diploma (B.S./M.S.), Chemical Engineering, Nat. Technical Univ. Athens, 2000 Committee Chair: Dr. Dionysios D. Dionysiou ii Abstract This dissertation explores the fundamentals of a novel advanced oxidation technology, the II cobalt/peroxymonosulfate (Co /KHSO5) reagent, for the treatment of persistent and hazardous II substances in water. Co /KHSO5 is based on the chemistry of the Fenton Reagent and proceeds via the generation of sulfate radicals, which similarly to hydroxyl radicals, readily attack and degrade organic and microbial contamination in water. Very few studies have exploited the reactivity of sulfate radicals for environmental applications. Compared to the extensively investigated hydroxyl radicals, sulfate radicals are not fully understood. Following this approach, the coupling of nine transition metals with hydrogen peroxide (H2O2), potassium peroxymonosulfate (KHSO5) and persulfate (K2S2O8) was also explored. The objective was again the generation of inorganic radicals and the efficient degradation of organic contaminants in water. -

E-mail: [email protected] 2School of Mechanical and Production Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore. E-mail: [email protected] Abstracts In this paper reports a three layered device that consists of a double spiral channel design for chemiluminsence (CL) detection and a passive micromixer to facilitate mixing of reagents. Compared to the design with a single spiral channel, the design with two overlapping spiral channels doubled the CL intensity emitted from the reaction. Furthermore, the addition of the passive micromixer improved the signal by 1.5 times. Luminol-based chemiluminescence reaction was used for the characterization of the device. This device was successfully used for the determination of L-cysteine and uric acid. Keywords: chemiluminescence, lab-on-chip, micro total analysis system, luminol, cobalt, L-cysteine, uric acid 1 Introduction Chemiluminescence (CL) detection methods do not require an excitation light source. -

(JCBGI) and C & D Technologies, Inc. (C&D), MWH Americas, Inc. (MWH) has prepared this request for an injection permit for groundwater treatment in the acid unloading area at the above referenced site. The purpose of the permit request is to provide information to the Wisconsin Department of Natural Resources (WDNR) for approval to conduct a pilot study and full-scale injection of sodium persulfate into the acid unloading area for treatment of volatile organic compounds (VOCs) in groundwater. BACKGROUND INFORMATION Soil and groundwater contamination were found to exist on the Facility property exceeding State environmental standards, based on the August 1999 Phase II Environmental Site Assessment (ESA) of the Facility. In May and June 2001, remedial action was completed for the on-site lead, PCB, and VOC impacted soils. A summary of the remedial activities is contained in the February 2002 On Site Remedial Actions Construction Completion Report. Approximately 400 tons of VOC impacted soil was removed during this investigation. Temporary wells were installed in July 2001 and November 2001 as part of the groundwater VOC characterization investigations documented in the June 2001 and October 2001 Work Plans, respectively. -
