The study investigates the sorption of cadmium and lead (Pb) by Nsukka urban soils, a Nigeria soil classified as an ultisol soil of tropics. Laboratory batch technique was utilized to investigate the effect of pH, temperature, contact time, and concentration on the adsorption process. Results showed that adsorption efficiency of the soils for Cd 2+ and Pb 2+ increased with increase in pH, temperature, and contact time but decreased with increase in concentration. The data from adsorption studydoi:10.13005/ojc/350312 fatcat:iakojv6dorhu3g4hnhhx2dzxgy
