چکیده
|
The presence of heavy metals in the environment, resulting from industrial wastewater discharges, causes considerable damage to the natural balance of the aquatic ecosystem when they exceed certain concentrations. during this study, we were able to eliminate the content of ni^2+ ions contained in synthetic wastewater samples by the adsorption technique on a hull substrate taken from the beaches of mehdia in morocco. the present study indicates that the envisaged adsorption decreased the efficiency of the retention of ni^2+ ions from 91.03% (6.5 ppm) to 52.36 (250 ppm) and the adsorption capacity of 13.67%. mg / g for 200 ppm. the mass effect of the adsorbent was of the order of 84.8% for a value of 2 g, the temperature was of the order of 95% for 328±2 k. and a yield of 89.15% for a ph of between 6 and 7 and of the order of 93.5% for a contact time of 180 min.
