The problem of waters pollution with heavy metal has become one of the serious problems. The release of heavy metals into the water has increased noticeably as a result of industrialization, and thereby lowered the quality of the environment to an alarming level. heavy metals can accumulate to toxic levels through the human food chain and the biosphere from the environment, which can disturb the biochemical processes and human health [1-3]. Due to the mobility and toxicity, the presence of copper ions in water represents a real inorganic contamination problem. Therefore, it is important to remove copper from effluents, before discharging them into water bodies. The objectives of the present study were: (i) to investigate and establish the optimum conditions of pH, sorbent dose, copper concentration and temperature for the sorption capacity and removal efficiency in non-competitive conditions; (ii) to model the kinetic and equilibrium of copper adsorption in order to evaluate the kinetic and isotherm parameters; (iii) to establish the level of reusability of the sorbents during consecutive sorption/desorption cycles. |
