Abstract

An efficient metal biosorbent was developed by immobilising fungal biomass within matrix of loofa sponge (FBILS). At biosorption equilibrium FBILS removed 137 mg Pb(II) g-1, which was 24.3% greater than 110 mg Pb(II) g−1 free fungal biomass. The equilibrium biosorption data fitted well the Langmuir model. The experimental data, when applied to the pseudo-first and second-order kinetic models, followed the second-order with r² 0.996. Metal desorption from the Pb(II)-laden FBILS with 50 mM HCl was 99%, and the regenerated FBILS was repeatedly used in seven biosorption-desorption cycles without significant loss in biosorption capacity. The study indicated high potential of FBILS for effective removal of Pb(II) from industrial wastewater.
