    Available on line at Association of the Chemical Engineers of Serbia AChE www.ache.org.rs/CICEQ Chemical Industry & Chemical Engineering Quarterly 19 (1) 25−35 (2013) CI&CEQ ASIM KÜNKÜL1 INVESTIGATION OF THE USE OF AMMONIUM ABDULVAHAP GÜLEZGIN2 1 ACETATE AS AN ALTERNATIVE LIXIVIANT IN NİZAMETTİN DEMİRKIRAN THE LEACHING OF MALACHITE ORE 1Chemical Engineering Department, Faculty of Solutions containing ammonia allow for selective leaching of copper from a Engineering, Inonu University, copper ore. In this study, the leaching and kinetics of malachite ore were Malatya, Turkey examined using ammonium acetate solutions as an alternative lixiviant. The 2Kırşehir Prison and Detention effects of some experimental parameters on the leaching of malachite ore House, Kırşehir, Kırşehir, Turkey were investigated. A kinetic model to represent the effects of these parameters SCIENTIFIC PAPER on the leaching rate was developed. It was determined that the leaching rate increased with increasing solution concentration, temperature and stirring UDC 546.56:66:549.743.12 speed, and decreasing particle size and solid-to-liquid ratio. It was found that the leaching reaction followed the mixed kinetic control model. The activation DOI 10.2298/CICEQ120113039K energy of this leaching process was determined to be 59.6 kJ mol-1. Conse- quently, it was determined that ammonium acetate solutions could be used as an effective leaching agent for copper extraction from malachite ore.

Metals are frequently produced after being ex- lues in the metal source pass into the solution by tracted from an ore or its concentrates because most dissolving in the leaching step [1,2].

  • Scope and Application Ammonium Acetate Solution Buffered at Ph 7.0 Is Used to Displace Exchangeable Cations in Agricultural Soils
    Ammonium Acetate Method Scope and Application Ammonium acetate solution buffered at pH 7.0 is used to displace exchangeable cations in agricultural soils. This method gives an estimation of plant-available base cations (potassium, calcium, sodium, and magnesium). For calcareous soils (pH > 7.4 and calcium carbonate > 0.5%), this method overestimates plant available calcium, and Normandin et al. (1998) suggested using ammonium acetate solution buffered at pH 8.5 to suppress dissolution of calcium carbonates. Summary This is the method indexed by the OSU Extension Service Nutrient Management Guides for cations. Two grams of air-dried soil sample is shaken with 20 mL of ammonium acetate solution, filtered, and cations in the filtrate are determined by ICP-OES. Equipment and Materials Balance (xx.xx g) 1L volumetric flask Weigh boat 50 mL polypropylene centrifuge tube with cap (Falcon tube) – 1 tube per sample Reciprocating shaker Filter papers – Whatman #1 – 1 per sample Collection funnels – 1 per sample Reagents Ammonium acetate (mw 77.08) Acetic acid Ammonium hydroxide Deionized water Procedure 1. Preparation of ammonium acetate extraction solution a. Add approximately 600 mL deionized water to 1L volumetric flask b. Measure 77.08 g of ammonium acetate into flask c. Bring to volume, mix well d. Check pH to ensure it is at 7.0. If not, adjust using either acetic acid or ammonium hydroxide 2. Weigh 2 g of air-dried soil into 50 mL tubes. Include one tube with CAL standard soil and one tube with no soil to be the method blank. 1 3. Add 20 mL of ammonium acetate extraction solution to each tube, including the CAL standard and method blank.

  • Nucleic Acid Precipitation from Dilute Solutions
    Protocol TD-P Revision 2.0 Creation Date: 6/10/2015 Revision Date: 3/6/2019 Nucleic Acid Precipitation from Dilute Solutions Introduction Glycogen is also an inert carrier used to increase nucleic acid recovery from alcohol precipitation. It is a preferred coprecipitant for solutions containing oligonucleotides or low concentrations of DNA or RNA, as it does not add exogenous nucleic acids like other coprecipitants, such as yeast RNA or tRNA. Glycogen, a highly purified branched chain carbohydrate, is insoluble in ethanol and isopropanol and forms a precipitate that traps nucleic acids. Upon centrifugation, the insoluble glycogen/nucleic acid precipitate forms a visible pellet that simplifies downstream sample processing. Glycogen, 20 mg/ml, may be used for the recovery of oligonucleotides (>8 bases) and low amounts of nucleic acids (≥20 pg) from diluted solutions. Materials Nucleic acid solution Glycogen, 20 mg/ml (GoldBio Catalog # G-090) 3M Sodium Acetate, pH 5.2 Isopropanol or ethanol Nuclease-free water or TE Buffer, pH 8 Method 1. Add 1/10 volume of 3M sodium acetate, pH 5.2 to the nucleic acid in solution. Note: 1/10 volume of 2M sodium chloride or 5M ammonium acetate may be substituted. 2. Add Glycogen Solution, 20 mg/ml to final concentration of 0.05-1 µg/µl. Note: For oligonucleotides, use a final concentration of 1 µg/µl. For DNA or RNA, use a final concentration of 0.05-1 µg/µl of Glycogen Solution. 3. Add 1 volume of isopropanol to the solution. Mix gently. Note: 2.5 volumes of ethanol may be substituted.

It is used as a non- denaturing solvent in the process of protein purification and is especially useful in purifying membrane proteins, which are often sparingly soluble or insoluble in aqueous solution due to their native hydrophobicity. It has low light absorbance in the ultraviolet region of the electromagnetic spectrum, which is useful for laboratory workers monitoring ongoing chemical reactions or protein-protein binding with UV/Vis spectroscopy. Buffer substances Description Code Application Ammonium sulfate precipitation is a common method for protein Ammonium Sulfate for molecular biology A3485 purification. As the ionic strength of a solution increases, the solubility of proteins in that solution decreases.
