Chromatography of alkaline earths and transition metals on tin(iv) arsenosilicate and arsenophosphate thin layers in buffered EDTA solutions

Journal Article · · J. Liquid Chromatogr.; (United States)
The complex forming ability of ethylene diamine tetraacetic acid at various pH values and the ion exchange behavior of tin(IV) arsenosilicate and arsenophosphate cation exchangers have been combined in a chromatographic study of some metal ions. As a result some interesting observations have been made, which have led to certain analytically difficult separations such as Ca/sup 2 +/ -Sr/sup 2 +/, Ca/sup 2 +/ -Ba/sup 2 +/ and Hg/sup 2 +/ from Cu/sup 2 +/, Ni/sup 2 +/, Zn/sup 2 +/, Co/sup 2 +/ and Mn/sup 2 +/.
