Level of contaminants (Nickel and Lead) in aquatic ecosystems has increased due to discharge of industrial effluents in water. Hence, there is a need to remove heavy metals (Nickel and Lead) from the water. For removing heavy metals from water, hybrid biosorbent (Almond shell and Pleurotus sajor caju) was prepared. To prepare a novel hybrid biosorbent (Almond shell and Pleurotus sajor caju) for the removal of nickel and lead from waste water the study was conducted in the department of chemistry, university of agriculture Faisalabad. The biomass was collected from local market of Chiniot. Hybrid matrix (Almond shell and Pleurotus sajor caju) and heavy metals (Nickel and Lead) were prepared. Waste water was interacted with the developed hybrid metals (Nickel and Lead) and hybrid bio sorbent (almond shell and P.sajor caju).The maximum adsorption capacity q(mg/g) of nickel and lead obtained at l0mgL-l concentration is in the following order; hybrid biosorbent(87)>P.sajor caju(65)> almond shell(54) and hybrid biosorbent(85)>P.sajor caju(57)>almond shell(45). The maximum uptake for nickel obtained by almond shell, P.sajor caju, hybrid biosorbent (56%), (66%), (90%) for lead and (47%), (61%), (89%) for nickel. The adsorption of nickel and lead follows the 2nd order kinetic model. FTIR spectra show that there are various functional groups, active sites present in hybrid biosorbent (Almond shell and Pleurotus sajor caju). Maximum absorption of lead occurs at pH 5 and nickel at pH 3. The sorptions of heavy metals (Lead and Nickel) follow the pseudo 2nd order kinetic model. From the whole analysis it is concluded that Hybrid biosorbent calm of microbial and plant waste biomass was extremely functional in exclusion of lead and Nickel from wastewater.
