Abstract

Pesticide is modern technology that assists in agriculture sector to enhance the quality of yields on crop production. However, it may contaminate in the soil and cause water pollution from the runoff as a side effect. The experiment on the treatment of water had been conducted by using ultraviolet (UV) light to treat water that contaiminate by metamifop. In this study, the objective is to study effect of hydrogen peroxide (H2O2) on the rate of photodegradation of metamifop with presence of Fe(II) ions. The experiment was conducted by using metamifop, Fe(II) ions and H2O2. Solutions that had been prepared with the presence of metamifop had been experimental in addition of Fe(II) ions and H2O2 solution in different concentration. The effect of the addition was measured by using UV-Vis spectrometer. The presence of Fe(II) ions and hydrogen peroxide increase the photodegradation rate of metamifop. Overall study shows that the highest rate of photodegradation occur when the concentration of Fe(II) ions and H2O2 are equal to the concentration of the metamifop. Nevertheless, it will give retardant effect to the rate of photodegradation if higher concentration of Fe(II) ions and hydrogen peroxide used.
