Performance of granular activated carbon to diazinon removal from aqueous solutions

Increasing use of pesticides and improper methods of sewage disposal will cause water resources pollution and extremely damaging effects on the environment. This study aimed at Performance of granular activated carbon to diazinon removal from aqueous solution and assessing the relationship between COD and diazinon concentration.
This study is as a cross - sectional and work was carried out in lab-scale. Firstly, diazinon concentrations 1, 5, 10, 20, 30, 40, 50, 100, 150 mg/l were prepared from Stock solution (1000 mg/L), and then their COD were measured. Optimum pH for 2-4-D removal was determined and its absorption rate in different concentrations was measured.
Findings: Results showed a relationship between COD and concentration. On the other hand, COD removal increased with passage of the time, so that maximum removal 88% at contact time of 50 min observed. Optimum pH for all concentrations was determined to be.
Discussion and According to present study it can be concluded that activated carbon have be high performance of diazinon removal from water. In addition, a significant relationship was observed between COD and diazinon concentration, so that direct.
