Abstract (PDF)
Graphical Abstract:
The degradation of diisopropyl methylphosphonate (DIMP) in aqueous solutions was studied using ultrasound irradiation with a fixed frequency of 26.6 kHz, following the first-order kinetic model. The experimental parameters, including the pH, the initial concentration of DIMP, the processing time, and the concentration of the additive CCl4 were investigated. The best degradation efficiency of 98% was observed at pH of 10, adding 0.8 g/L CCl4 for a processing time of 45 min.
