Novel Procedure for Detection of Some Heavy Metal Ions in Shrimp Pond by Liquid Phase Extraction with Sodium Acetate

A pre-concentration procedure for liquid phase extraction with sodium acetate and cyclic voltammetric determinations of some heavy metal ions in shrimp pond is presented in this work. In order to achieve accurate, sensitive and reliable results, pre-concentration and separation are needed when the concentrations of analyte metal ions in the primitive material or the prepared solutions are too low to be investigated. The effectiveness of analytical parameters such as pH of the sample solution, flow rate of sample and eluent solutions, sample volumes, on the recoveries of copper and lead were determined. The influences of co-ions were also examined. The presented pre-concentration procedure was used for the determination of metal ions in reference standard material and real environmental samples in sediment.
