The hen egg shells (HES) from EnShi, HuBei Province, China, which contain selenium, are used as adsorbent for the adsorption of lead ion from its aqueous solutions. The selenium in the HES could help to remove lead from its aqueous solution. The HES had been found to be the more efficient in the experiment and removed about 95% of lead from its aqueous solution. The final concentration of lead ion was found lower than the waste water quality standards from the initial concentration of lead ion 100.0 mg/L through these two steps of adsorptions. One gram of the HES can adsorb nearly 31.71±0.040 mg of lead ions. The adsorption kinetics was fitted by first-order model throughout the period. The present adsorption process is spontaneous, indicating HES can be availably used for the removal of lead ions from its aqueous solution.

Modified Diatomite

Fe-diatomite was prepared and applied for the sorption of Pb (II) from aqueous solution. The samples before and after modification were characterized by SEM and XRF. The results showed that iron hydroxide compound has been successfully loaded at the diatomite. Lead adsorption characteristics were studied in a batch system with respect to changes in initial concentration of lead, pH of solution, adsorbent dosage and temperature. It showed that the removal rate increased with pH, adsorbent additive amount, the temperature and decreased with the initial concentration.
