摘要：One of the important sources of environmental pollution is heavy metals of industrial wastewater which areharmful for human health and environment. Therefore, the purpose of this research was to investigate theremoval of Cd from aquatic solution by tartaric acid modified sesame husk. This research was an appliedand experimental type. The effects of pH, initial adsorbent concentration, initial metal ion concentration andcontact time were studied in batch experiments. The result showed that the Cd removal efficiency increasedby increase in adsorbent dosage, pH (up to 5) and contact time and decrease in Cd concentration. Inoptimum condition, modified sesame husk removed 99% of Cd from aqueous solutions. The equilibriumdata were best fitted on Freundlich isotherm and the adsorption kinetic model followed a pseudo-secondmodel. ANOVA showed that there was a significant difference between variables and Cd removal. Accordingto the results obtained, modified sesame husk appears to be suitable, low cost and efficient adsorbent forremoving Cd from aqueous solutions.
