Diaion SP-850 resin as a new solid phase extractor for preconcentration-separation of trace metal ions in environmental samples.

A solid phase extraction method was developed for the preconcentration and separation of trace amounts of chromium, manganese, iron, cobalt, copper, cadmium and lead from environmental samples by complexation with alpha-benzoin oxime followed by adsorption onto Diaion SP-850-solid phase extraction column. One molar per liter HNO(3) was used as eluent. The… CONTINUE READING
