Solid phase extraction technique in analytical chemistry (A new preconcentration and separation method for the determination of trace heavy metal ions in natural samples)

Abstract

Solid phase extraction technique is found a wide application in analytical chemistry as a preconcentration and separation of trace metal ions in complex matrixes in recent years. The method is efficiently, very simple and needs simple equipments, not more chemicals. Their enrichment factor is very high by the determination of heavy metal impurities in water. Therefore it is a useful and cheap technique especially for the laboratories; they have not enough good sensitive analytical instruments like GFAAS, ICP- MS or TXRF.
