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).
