Water pollution has an adverse effect on environment, and it can reflect dangerous results on human health. To overcome this emerging problem, researchers are still exploring different new technologies to improve water purification methods with low cost. The newly emerging nanotechnology provides a potential to purify water with high efficiency and reusability. Therefore, the main objective of this study was to evaluate the efficiency of a novel, inexpensive and eco-friendly nano-composite in removing selected heavy metals from contaminated wastewater. To achieve such objective, synthesis of nano-composite {Zeolite (Ze)-nano water treatment residual (nWTR) was performed along with equilibrium, kinetics and thermodynamic studies of Cd and Pb sorption by the novel nano sorbent
