DDT REMOVAL BY NANO ZERO VALENT IRON: INFLUENCE OF pH ON REMOVAL MECHANISM

Abstract

Persistent organic compounds are resistant to
biological degradation and can be transported long distances by releasing into
the atmosphere and can be found in the atmosphere for a long time. DDT is one
of the persistent organic compounds which is prohibited by Stockholm
Convention. Against the prohibition in many countries, DDT, which is still in
limited use in undeveloped countries, has a very low carcinogenic concentration
(0,23 μg/L). It is stated in the literature that nanomaterials have been used
effectively in the last decades for the removal of environmental pollutants. In
this study, the mechanism of removal by nano zero valent iron was investigated
by researching the pH effect at low DDT concentration. pH and ORP changes after
treatment were investigated. Almost total DDT was removed within 5 minutes and
pH effect on removal mechanism has found to be negligible. The ORP values
decreased rapidly during the first minutes of the study. In addition, the
effluent Fe2+ concentrations were also investigated and these
results showed that oxidation was effective in the removal mechanism.
