Adsorption of cadmium by using regular Zn-AlC0₃ hydrotalcite / Zuritah A.Kadir

Heavy metals pollution is very serious problem in waste water pollution around industrial area. In this study, Zn-AlCO₃ LDH was investigated as an alternatively low-cost adsorbent for the adsorption of cadmium in aqueous solution. Zn-AlCO₃ LDH with ratio 4 was synthesis by co-precipitations method a...

The optimum contact time was 120 minutes with 40 mg/L initial concentration. The percentage uptake of cadmium increases with initial concentration, adsorbent dosage and temperature.
