Abstract:
Phosphate is one of the essential elements in the earth but the excessive amount of
phosphate can contribute to the environmental problems. Adsorption is one of the
most effective and ecomical technique to removes phosphate in wastewater.
Nowadays, researches have been discovered the potential and beneficial of the
agricultural waste as a low cost adsorbent. This study aimed to prepare and
characterize the efficiency of rice husk as biosorbent for phosphate removal in
wastewater. Six type of adsorbent were prepared, which are Rice Husk Ash and
Activated Rice Husk at five different temperature. The prepared adsorbents were
characterized in term of functional group by using FTIR Spectroscpe and in term of
morphology structure by using SEM method
