PH effect on the photocatalytic degradation of the chlorpyrifus form insecticide morisban4 by zno in aqueous medium

الملخص EN

The effect of pH on the photo degradation of the chlorpyrifus form insecticide “MORISBAN4" in an aqueous environment, using ZnO catalyst was studied.

It was found that the rate of the photo degradation process of the insecticide was dependent on the pH values.

A photo degradation processes at three different pH values 4, 7, and 10 were studied.

A rapid degradation process for the chlorpyrifus form insecticide was obtained when the pH value was 4, in other words in moderate acidic medium.

The rate constant (K), half-life (t1 / 2) for the degradation processes at different pH values were calculated.

The method for the photo catalytic degradation process in the presence of sunlight is described within.
