Abstract:

A preconcentration/separation procedure is presented for the solid phase extractionof trace cadmium and lead ions as their 2-propylpiperidine-1-carbodithioate (PPCD) chelates inenvironmental samples on Nano Graphene, prior to cadmium and lead determinations by atomicabsorption spectrometry. The preconcentration procedure was optimized by using model solutionscontaining cadmium and lead ions. The influences of pH of the model solutions, amounts of PPCD,eluent type and volume etc. were investigated. Also the effects of the matrix constituents of the sampleswere also examined. Separation of cadmium and lead from real samples was achieved quantitatively.The procedure presented was checked with the analysis of standard reference materials (IAEA-336Lichen and SRM 1515 Apple leaves). The preconcentration procedure was applied for the lead andcadmium contents of the natural water samples, some salts with satisfactory results (recoveries >95%,relative standard deviations <7%).
