Retention behaviour of metal ions on calcium sulphate layers: separation of mercury

摘要

Calcium sulphate static phase thin layer chromatography (TLC) has been performed in eight pure and mixed solvent systems containing acetonitrile and dioxane. Separations of Pb~(2+) from Hg~(2+), Bi~(3+) and UO_2~(2+); UO_2~(2+) from VO~(2+); Ni~(2+) from Cr~(3+); Ag~+ from Bi~(3+); Ce~(4+) from Ce~(3+); Hg~(2+) from Cd~(2+); Zn~(2+); from Hg~(2+) have been achieved successfully. Rapid quantitative separation of mercury (2-20 #mu#g) from binary, ternary and multicomponent mixtures containing several metal ions has also been successfully achieved.
