adsorption tests were performed to evaluate the lead from the sewage irrigation soil as a function of reaction time, initial concentrations, competition ions, humic acid and pH. A kinetic adsorption test... samples of 1.0 g in duplicates were equilibrated with 40 mL of the solutions in 50 mL polyethylene centrifuge tubes. Firstly, during the adsorption kinetic test for the reaction time, all the experiments......
