【 摘 要 】

Nanoparticles of metal oxide have great potential in the photocatalytic system for removal of heavy metals in wastewater. The usage of titanium dioxide (TiO2) as photocatalyst has gained much attention because of its unique properties compared to others metal oxide. The usage of activated carbon (AC) as adsorbent from agricultural wastes such as coconut shell, cotton stalks and rice husk (RH) has recently used nowadays due to it is characteristic and low cost. Besides, it can reduce the abundant of wastes from open burning occurs and also can minimizing air pollution. The combination of photocatalyst-absorption process has been introduced in photocatalytic activity via dip-coating techniques without involving the filtration process. This technique has seeking more attention of researchers for removal of heavy metals such as cadmium (Cd), chromium Cr) and copper (Cu) in industrial wastewater treatment.
