Abstract
The objective of the study is to evaluate modifiedcarbon screenprinted working electrodes SPE combined with square wave anodic stripping voltammetry SWASV to determine electrolabile and total copper in soils with the perspective to assess the environmental hazard resulting from copper anthropogenic contamination The voltammetric method was investigated using a mineralized certified reference soil such that it can be assumed that the copper was totally under electrolabile form in the solution of mineralized soil In optimal conditions a copper recovery of 97 and a relative standard deviation RSD of 9 were found The limits of detection and quantification for copper were 04 and 13 μg L−1 respectively Finally the method was applied on soil leachates which allowed evaluating the cupric transfer from the soil to the leachates and quantifying the electrolabile copper part in leachates
