G. Jallan et Gs. Pandey, DE-IONIZATION PROCESS OF PB-2-2+ IONS IN SEWAGE ENVIRONMENT( AND ZN), Journal of environmental biology, 15(2), 1994, pp. 83-88
The self-regulated process of de-ionisation of heavy metal ions such a
s Pb2+ and Zn2+ in the domestic sewage sludge has been studied by equi
librating the sludge with respective metal ions, and determining their
concentrations after specific intervals of time. While total eliminat
ion was observed in case of Pb2+ ions, a substantial decrease was foun
d in case of Zn2+ ions.
