Degradation of Ammonium butyl-dithiophosphate by Fe²⁺/NaClO Process

Abstract:

The initial pH, initial concentration of Fe²⁺ and NaClO on the degradation of ammonium butyl-dithiophosphate using Fe²⁺/NaClO process have been investigated in this paper. The results shows that under the optimum reaction conditions of a temperature 28°C, pH 4.0, the initial concentration of Fe²⁺ and NaClO is 15 mg/L and 5.33 mL/L, respectively, about 87.86% ammonium butyl-dithiophosphate removal can be achieved within 150 min by using a Fe²⁺/NaClO process. The degradation of ammonium butyl-dithiophosphate under different NaClO concentration conditions follows the first order exponential decay equations. The Fe²⁺/NaClO can efficiently oxidation of ammonium butyl-dithiophosphate in aqueous solution and can be an effective process for the treatment of ammonium butyl-dithiophosphate wastewater.
