Performance of cellulose-diethylenetriamine as binding layer in the diffusive gradients in thin films method for measurement of Cu in environmental waters

Abstract

Abstract Palu Bay and Poboya River, Central Sulawesi, Indonesia, was an environmental waters near site to the location of traditional gold mining and residential areas. This research aimed to apply of cellulose-diethylenetriamine material as a binding layer on the diffusive gradients in thin films method to evaluate the distribution copper labile species release into Palu Bay and Poboya River. On this method, influence of ionic strength, pH, initial concentration, gel thickness were evaluated. The results showed that the concentrations of copper labile metal measured by DGT method could be significantly different, indicating that the labile fractions of copper metals were adsorbed well on the functional group of the binding agents. By choosing cellulose-diethylenetriamine as binding layer, the proposed approach was successfully employed measurements in the aquatic system.
