Extraction of cadmium from solutions containing various heavy metal ions by Amberlite LA-2
Journal of Industrial and Engineering Chemistry, 2010Abstract In present study, selective extraction of cadmium from acidic leach solutions, containing various heavy metal ions, by emulsion liquid membrane (ELM) is studied. For this reason, the zinc plant copper cake was leached with sulfuric acid and main acidic leach solution containing Zn(II), Cu(II), Fe(II), Cd(II), Co(II) and Ni(II) ions was ...

The present study is on the reactive extraction of picric acid (HPc, 2,4,6-trinitrophenol) from dilute aqueous solutions by organic phases containing Amberlite LA-2 (ALA-2) as extractant dissolved in four types of ketones. The studies were performed at 298, 308, and 318 K, and the results were used to calculate the values of distribution coefficient ...

This study presents a simple and effective method for extracting carmine dye from its aqueous solutions using Amberlite LA-2 liquid extractant. The effect of several operating factors on extraction efficiency was studied, such as Amberlite concentration (0.011, 0.022, 0.044, 0.088, 0.132), initial dye concentration (20, 40, 60, 80, 100, 140), contact ...
