Investigation of leaching kinetics of zinc from a low-grade ore in organic and inorganic acids
The leaching kinetics of a low-grade zinc oxide ore in different acid media was investigated with respect to the experimental variables including acid concentration, temperature, liquid to solid (L/S) ratio, and stirring speed. The results obtained showed that the leaching reagent concentration and the reaction temperature exerted significant effects on the extraction of zinc, whereas the L/S r...
متن کاملeffects of low-molecular weight organic acids on phosphorus sorption in some calcareous soils
the effect of 0, 2, and 5 mm of citric, malic and oxalic acids on phosphorus (p) sorption was evaluated. in the collected soils, the level of total calcium carbonate stood in the range of 4-28%, clay content at 33-56% and the amount of organic matter recorded within 0.6-2.7%. the results indicated that the addition of organic acids causes reduction in p sorption. citric acid in most soils, was ...
متن کاملDetermination of organic acids of low molecular weight and phosphate in soil by capillary electrophoresis.
Capillary zone electrophoresis with indirect UV detection at 254 nm was found to be suitable for the determination of organic acids and phosphate in aqueous extracts of soil. The best support electrolyte solution was found to be 10 mM p-hydroxybenzoic acid with 0.5 mM tetradecyltrimethylammonium bromide to reverse electroosmotic flow. This methodology was tested with 9 analytes found in soils: ...
متن کاملStability of Chloropyromorphite in Ryegrass Rhizosphere as Affected by Root-Secreted Low Molecular Weight Organic Acids
Understanding the stability of chloropyromorphite (CPY) is of considerable benefit for improving risk assessment and remediation strategies in contaminated water and soil. The stability of CPY in the rhizosphere of phosphorus-deficient ryegrass was evaluated to elucidate the role of root-secreted low molecular weight organic acids (LMWOAs) on the dissolution of CPY. Results showed that CPY trea...
