EFFECT OF CARBONIZATION ON BANANA PEELS FOR REMOVAL OF CADMIUM IONS FROM AQUEOUS SOLUTION

摘要

Adsorption studies of cadmium(II) were conducted on 623 degrees K or 723 degrees K carbonized banana peels named as BP623 and respectively BP723 as well as on the dried ones (BP). Carbonization enhances the quality of organic by-product used as adsorbent, reduces the equilibrium time and improves the quality of the final product (water). Evaluation of the effects of pH, contact time and solution temperature showed that the uptake of cadmium(II) ions was highly dependent on these factors, and increased with increasing pH and solution temperature.
