Sorption of cadmium (II) and zinc (II) from halide and thiocyanate solutions by means of unmodified and basic dye-modified silica gels

摘要

The sorption of cadmium (II) and zinc (II) from halogenic and thiocyanate solution onto silica gel modified and unmodified with bases dyes-Brilliant Green and Methyl Violet was studied. The optimal conditions of sorption separation of ions cadmium (II) and zinc (II) was established. The sorption-atomic-absorption procedure for determination of cadmium (II) in standart samples of zinc alloys was developed. The procedure was used on model solutions of galvanic sawages.
