Anaerobic Sulphate-Reducing Microbial Process Used for Sorbent Preparation

Abstract

The presence of metals in waters represents today typical anthropogenic pollution. Their increased content, originating in various industry sectors and previous mining activity, is undesired. High concentrations of metals are hazardous for all living organisms. They may accumulate to toxic levels, cause many disorders and diseases and ecological damage under certain environmental conditions. Sulphate-reducing microbial process utilization is one of the options to prepare applicable sorbent which removes metal ions from solutions. This sorbent is created as a consequence of sulphate-reducing bacteria metabolism in anaerobic environment. It is considered to be able to remove many metals from solutions, such as Zn, Cd, Pb, Cu, Ni, As.
