Major-to-Ultratrace Element Analysis of Environmental Water Sample around Sewage Treatment Plant by Using ICP-MS with the Aid of Chelating-resin Solid Phase Extraction

Analytical method for the determination of major-to-ultratrace elements in environmental water samples around sewage treatment plant by ICP-MS was examined detail. In present work, solid phase extraction using chelating-resin adopted as preconcentration ultratrace elements. Prior to extraction, were heated with nitric acid and hydrogen peroxide at 200 °C 4h decompose chelating agents contained effluent such EDTA, which cause low recovery values several As a result, 53 concentration range from sub-ng/L 10 mg/L could be determined good reproducibility. The reliability whole analytical procedure confirmed analyzing river certified reference materials (JSAC 0301-4a JSAC 0302-4a). From results (river water) (upstream, just below outlet, downstream 1 2), it found that various Fe, Co, Ni, Cu, Zn, Cd, Pb emitted into dissolved forms, while element existed mainly particulate matters (Al, Ti, rare earth elements) showed concentrations effluent. Distribution patterns characteristic large Gd anomalies increase light REE heavy REE, same other affected influx
