摘要：In this study,abundant and low coast natural clay is tested for its ability to retain copper cations.The experiments have been carried out batch wise and the influence of physico-chemical key parameters such as the solution pH, the temperature,etc.The obtained experimental results have been fitted according to the two known adsorption models of Langmuir and Freundlich.The adsorption depending on the temperature shows that the amount adsorbed by the clay increases with the increase of temperature, the thermodynamic parameters shows that the retention process was spontaneous, endothermic and involves two mechanisms: adsorption and ion exchange
