| Abstract | ||
| The effective removal of heavy metal ions from water is among the most important issues for many industrialized countries. The present work has been carried out to study the adsorption of cobalt [II] ion using activated carbon. The removal of cobalt ions was investigated in batch conditions. The influence of initial cobalt ion concentration, pH, adsorbent dose, adsorbent practical size; contact time and shaking rate were studied at room temperature. The analysis of residual Co [II] ions was determined using Atomic Absorption Spectrophotometer GBC 933 plus. The results showed that the percentage adsorption of activated carbon increases with time and that maximum adsorption was obtained within the first 60 minutes of the process, and 300 rpm shaking rate. The experiments showed that the maximum % adsorption of 100% was obtained at adsorbent dose=0.4 gm, pH=13, particle size= (0-75) μm and 10 mg/L of initial concentration of cobalt. These results indicate that activated carbon has potential for removing cobalt ions from water. | ||
