Extraction of indium, cadmium and thallium by salts of dinonylnaphthalene sulphonic acid was studied from sodium, potassium and calcium media. The results showed that HD and its salts formed aggregates and behaved as liquid cation exchangers. The extent of aggregation was studied by vapour pressure osmometry. A comparison was also made using analogous solid cation exchangers.
