Dicofol, a recommended Stockholm convention persistent organic pollutants (POPs) candidate is well known for its endocrine disruptive properties and has been extensively used as an organochlorine pesticide worldwide. The hydrodynamic cavitation (HC) treatment of Dicofol in aqueous media induced by a liquid whistle hydrodynamic cavitaion reactor (LWHCR) has been investigated while considering important parameters such as inlet pressure, initial concentration of Dicofol, solution temperature, pH, addition of H₂O₂ and radical scavenger for the extent of degradation. The pseudo-first-order degradation rate constant (k) was determined to be 0.073 min⁻¹ with a cavitational yield of 1.26 × 10⁻⁵ mg/J at optimum operating conditions and a complete removal of Dicofol was achieved within 1 h of treatment. Considering the removal rate and energy efficiency, the optimal inlet pressure was found to be 7 bar, resulting in a cavitation number of 0.17. High performance liquid chromatography (HPLC) and Gas chromatography mass spectroscopy (GC–MS) analyses indicated a sharp decline in the concentration of Dicofol with treatment time and indicated the presence of degraded products. An 85% total organic carbon (TOC) removal was achieved within 1 h of treatment time, demonstrating successful mineralization of Dicofol. The obtained results suggest that the degradation of Dicofol followed thermal decomposition and successive recombination reactions at bubble-vapor interface. Overall, the attempted hydrodynamic cavitation demonstrated successful and rapid removal of endocrine disruptive chemicals such as Dicofol and is expected to provide efficient solution for wastewater treatment.

Dicofol是斯德哥尔摩公约推荐的持久性有机污染物（POPs）候选物质，以其内分泌干扰特性而闻名，已在全球范围内广泛用作有机氯农药。在考虑重要参数（例如入口压力，Dicofol的初始浓度，溶液温度，pH值，H ₂ O的添加）等重要参数的情况下，研究了液体哨声流体动力反应器（LWHCR）在水介质中对Dicofol进行的流体动力空化（HC）处理。₂，自由基清除剂的降解程度。拟一级降解速率常数（k）确定为0.073 min ^-1，空化产率为1.26×10 ^-5 mg / J在最佳操作条件下，并在处理1小时内完全清除了Dicofol。考虑到去除率和能量效率，发现最佳进口压力为7 bar，导致气穴数为0.17。高效液相色谱（HPLC）和气相色谱质谱（GC-MS）分析表明，随着处理时间的延长，三氯杀螨醇的浓度急剧下降，并表明存在降解产物。在处理时间1小时内，去除了总有机碳（TOC）的85％，这证明了三氯杀螨醇的成功矿化。获得的结果表明，三氯杀螨醇的降解遵循热分解和气泡-蒸汽界面的连续重组反应。全面的，
