In this study, humic acid which contains both hydrophobic and hydrophilic moieties is successfully entrapped in sol-gel matrix which is used to reduce the chemical oxygen demand (COD) of Gaza wastewater. The method was very efficient in which more than 90% reduction of the COD had been achieved, it was found that contact time with the matrix, temperature, pH, particles size, adsorbent dose, and agitation speed effect the COD reduction.

 

Key words: Wastewater, humic acid, COD, sol-gel.
