摘要：Natural products like phosphates have varied physico-chemical and textural properties. They are able of establishing connections with various sizes of organic or inorganic molecules. Recent studies showed that these materials in the natural or synthetic state can eliminate many co mpounds present in waste water. In this work, we have tried to estimate the efficiency of elimination of co pper by adsorption on natural phosphates and synthetic materials. Activated carbon is used as a reference. The kinetics of adsorption is followed by UV -visible spectroscopy. Several parameters are controlled and studied using experimental design (pH, temperature and the initial concentration of pollutant and phosphates). Physical treatment is made to increase the adsorption capacity of these materials. The obtained results show that the adsorption follow Langmuir model and the capacity of adsorption o f these materials is equal to the activated carbon.
