Feasibility Of Metal Biosorption using Gulmohar (Delonix Regia) Tree Leaves Power: Effect Of Biosorption Structure On Adsorption Isotherms And Kinetics

Abstract

In this work, biosorption process was commited for expulsion of metals using Gulmohar tree leaf powder since Gulmohar tree leaf powder (GTLP) is a efficient biosorbent for treating Cr(VI) ions. The optimum values observed for efficient removal of Cr(VI) ions were pH-2, concentration for Cr(VI) biosorption by GTLP- 20 ppm and biosorbent dosage-0.1 g. The symmetry was attained at 75 min of acquaintance time. Experimental values were depicted with Freundlich and Langmuir models. Sorption equilibrium exhibited good robust to Langmuir model (R2 = 0.991).
