Study of adsorption of copper on biomass pleurotus mutilus and the possibility of its regeneration by desorption

It is very well known at present that different industries agro-food sector generally produce considerable quantities of wastewater should be treated imperative for preserving the environment, and thus avoid a real danger to the ecosystem. These waters are usually loaded with in pollutants of organic nature. There are important quantities of biological materials, few or badly recovered, which are capable of adsorbing metals dissolved in effluents. These residues consist primarily of industrial fermentation sludge pleuromitiline cultivated to produce enzymes, antibiotics.... This study was motivated by the fact that no quantitative study concerning the physico-chemical behaviour of Pleurotus mutilus, hence the idea to use the capacity of retention by adsorption of contaminants. The purpose of this paper is to study the adsorption of copper on biomass pleurotus mutilus treated. We studied the possibility of regeneration of biosorbent. For that several parameters were optimized: the nature of the desorbent, the pHi, and the content of biomass desorbs.... This study was completed by determining the new capacity of biosorption after regeneration of biomass.
