Aminated Desmostachya bipinnata - Potential Biopolymer for the Removal of Lead Metal Ions from Wastewate

Authors(2) :-Jagjit Kour, Bindra Shrestha and Kedar Nath Ghemire

The biopolymer from Desmostachya bipinnata (DB) is investigated as a potential bio-adsorbent for the removal of Pb (II). It is a holy herb of the South Asian region with medicinal value. DB was functionalized with two types of aminating agents, which created suitable metal chelating medium encountered in aqueous solution. The biopolymer was characterized with SEM, DRFTIR, elemental analysis, zeta potential, and TG/DTA, which indicate functionalization with amine groups. The effect of pH, initial concentration and contact time of the metal solution were monitored by batch method. The maximum adsorption capacities were found to be 130.40 mg/g and 87.20mg/g, respectively. Langmuir isotherm model fitted well and the rate of adsorption followed the pseudo second order kinetic model. Desorption experiments result in regeneration of about 92 % Pb (II). The regenerated biopolymers were used for six successive cycles without any significant decrease in adsorption and desorption. Thus, the biopolymer derived from DB can be used as a cost effective, efficient and environment friendly green material for the removal of Pb (II) from the waste water.
