Abstract: Adsorption is one of the best technologies for the removal of nickel and lead water decontamination because it is an efficient, cheap and eco friendly treatment method. It is a good technique strong adequate to recognize water reuse requirement and high overflow standards in the industries. In the present work Cinnamomum Camphora seeds powder was studies as adsorbent for the removal of nickel and lead ions from aqueous solutions. The batch adsorption studies were carried out to examine the adsorption of nickel and lead on Cinnamomum Camphora seeds powder for the effect of initial concentration, contact time, adsorbent dosage, pH, temperature and also studied thermodynamic parameters. The maximum adsorption removal of Cinnamomum Camphora seeds powder was found to be 90 % and 91 % for lead and nickel at the initial concentration of 50 mg/L. For the effect of temperature, the percentage removal of lead and nickel was noticed as 92 % and 96 % at the temperature of 62oC. The removal of nickel ions decreased with increasing in pH, thus pH of 10, which gives maximum percentage removal of nickel, is 90 % and for lead is 89 % at the optimum pH of 6. The adsorbent dosage of Cinnamomum camphora seeds powder increases with increasing the percentage removal of lead and nickel and it is found to be 88 % and 85 %. The correlation coefficient of Langmuir model for lead and nickel were found to be 0.986 and 0.9936 and the correlation coefficient of Freundlich model for lead and nickel were found to be 0.9905 and 0.9647 respectively. The Langmuir adsorption model which exhibited outstanding indication of adsorption data than the Freundlich adsorption model for Cinnamomum Camphora seeds powder in the nickel. The plot of log qe/ce versus 1/T was obtained with R-squared value 0.988 and 0.985 for nickel and lead.
