The effects of the chemical composition and particle size, of suspended particles in river water, on the adsorption of lead onto these particles have been studied. Lead has been determined using the conventional method of anodic stripping voltammetry. Particle sizes have been determined using the Coulter Counter. The organic matter content of the suspended particles has been found responsible for most of the lead adsorbed onto these particles. An attempt has been made to quantify the relationship between the particle size of suspended particles and the amount of lead adsorbed onto these particles. The shape of the calibration graphs of lead from solutions in river water has been explained with reference to the adsorption of lead on suspended particles.
