Removal of Lead from Water by Adsorption on a Kaolinitic Clay
The possible use of kaolinitic clay, Giru day, from Nigeria as an adsorbent for the removal of lead from water was investigated. Studies were carried out as a function of contact times, concentrations, temperatures and pH. The kinetics of adsorption as well as adsorption isotherms at different temperatures were equally studied. The results show that lead removal is favoured by low concentration, high temperature and acidic pH. The reasons for these observations are adduced.
