Blog Article

The spectrophotometric determination of Cd(II) using a flow injection system provided with a solid-phase reactor for cadmium preconcentration and on-line reagent preparation, is described.It is based on the formation of a dithizone-Cd complex Mass Balance of Cenozoic Andes-Amazon Source to Sink System—Marañón Basin, Peru in basic medium.The calibration curve is linear between 6 and 300 µg L-1 Cd(II), with a detection limit of 5.

4 µg L-1, an RSD of 3.7% (10 replicates in duplicate) and a sample frequency of 11.4 h-1.

The proposed method was satisfactorily applied to the determination of Cd(II) in surface, well Local models for rainstorm-induced hazard analysis on Mediterranean river-torrential geomorphological systems and drinking waters.
