ABSTRACT
Aims:
The objective of the work is to remove Pb2+ by Pleurotus florida and Trichoderma viride in batch studies and to study the kinetics and adsorption isotherm of Pb2+ adsorption by fungal species and to determine the desorption performance by suitable desorbing agents. StudyDesign:
Experimental study. Place and duration of the study This work was carried out at Department of Biotechnology, Government College of Technology, Coimbatore, Tamil Nadu, and India for a period of five months.Methodology:
The polluted sample was collected from Valankulam lake, Coimbatore. The biomass of Pleurotus florida and Trichoderma viride were used as adsorbents. Atomic Absorption Spectrophotometer was used to quantify Pb2+ concentration. The optimum conditions of pH, adsorbent dose and contact time for biosorption were determined.Results:
Maximum adsorption of Pb2+ for Trichoderma viride and Pleurotus florida were observed at a pH of 6 and 7 respectively. The optimum quantities of adsorbent required for the removal of Pb2+ were 0.2g for both the organisms. Adsorption of Pb2+ was found to reach equilibrium in 1 h and 1.5 h for Pleurotus florida and Trichoderma viride respectively.Conclusion:
Hence, Pleurotus florida and Tricoderma viride are suitable adsorbents for the removal of Pb2+ from effluents. This methodology can be used for the removal of lead from waste water before its disposal.
