Voltammetric Approach in Soil Analysis for Trace Metals at Sub-fig Concentrations

摘要

Low level concentrations of copper,molybdenum,zinc and vanadium were determined in soil samples using differential pulse polarography.The comparison of results obtained by DPP suggests the validity of the analysis.Most applications of chemical analysis to real samples of water and soil involve trace determinations at a level of parts per million(ppm)or parts per billion(ppb).
