Project Details


The aim of this project is to obtain methods for differentiation between poisonous and non-poisonous metallic species in the environment. In contrast to conventional PSA, where the reoxidation of the prereduced/preconcentrated analytes in the mercury film of the working electrode is based on the use of mercury ions, this project is concerned on finding alternative means of oxidation thereby obliviating the use of mercury ions and hence make the method more environmentally acceptable. This is much in demand, because the method as such is a simple, inexpensive and expedient approach for trace level determinations as compared to the more costly optical procedures commonly applied.
