Flow injection on-line solid phase extractive preconcentration of palladium(II) in dust and rock samples using exfoliated graphite packed microcolumns and determination by flame atomic absorption spectrometry

Praveen, R S; Sobhi Daniel; Prasada Rao, T; Sampath, S; Rao, K S (Elsevier, 2006)

A sensitive and efficient flow injection preconcentration and matrix-separation technique using exfoliated graphite (EG) as column material was developed prior to flame atomic absorption spectrometry (FAAS) determination ...
Solid phase extraction vis-a-vis coprecipitation preconcentration of cadmium and lead from soils onto 5,7-dibromoquinoline-8-ol embedded benzophenone and determination by FAAS

Prasad, K; Gopikrishna, P; Kala, R; Prasada Rao, T; Naidu, G R K (Elsevier, 2006)

This article compares the solid phase extraction (SPE) and coprecipitative preconcentration of cadmium and lead from dilute aqueous solutions as a function of pH and weight of chelating agent. SPE enriches cadmium and lead ...
