Kinetics of the adsorption of lead on river-mud

Abstract

The effects of several factors on the rate and the capacity of lead adsorption by river-mud were studied. These factors included the concentration of mud, the concentration of lead, the organic matter content of mud, pH, time of adsorption, temperature and agitation. The reaction order of the adsorption process with respect to lead and the type of adsorption were determined. Also, indications of the rate-limiting step were discussed and an empirical equation describing the adsorption of lead on river-mud was developed.
