摘要

本研究首次利用磁场下的活性过硫酸盐(PS)研究了亚甲基蓝(MB)降解和矿化过程的有效性。研究评估了各种操作参数的影响,包括 pH 值、PS(5-20 mg/L)、磁场强度(1-4 A)、亚甲基蓝染料的初始浓度(25-100 mg/L)和接触时间(30-120 分钟)。通过田口模型对工艺进行了优化,发现这些因素的最佳值为 pH = 5、PS = 10 mg/L、MFs = 4 A、反应时间 = 30 分钟和亚甲基蓝染料的初始浓度 = 50 mg/L。在最佳条件下,亚甲基蓝去除率和 TOC 破坏率分别达到 91.8% 和 88%。该过程的动力学遵循假二阶(R2 = 0.9723)。研究结果表明,使用磁场净化染料的效率比不使用磁场时提高了约三倍。建议将该系统用作纺织工业的废水处理工艺,以降低废水的毒性和总有机碳(TOC)。

Enhanced methylene blue degradation and miniralization through activated persulfate coupled with magnetic field
In this work, for the first time, the effectiveness of the degradation and mineralization process of methylene blue) MB) was investigated using activated persulfate (PS) with a magnetic field. The effect of various operating parameters, including pH, PS (5–20 mg/L), intensity of the magnetic field (1–4 A), initial concentration of methylene blue dye (25–100 mg/L), and contact time (30–120 min), was evaluated. Process optimization was conducted via the Taguchi model, and the optimal values of these factors were found to be pH = 5, PS = 10 mg/L, MFs = 4 A, reaction time = 30 min, and the initial concentration of methylene blue dye = 50 mg/L. Under optimal conditions, the methylene blue removal efficiency and TOC destruction efficiency reached 91.8% and 88%, respectively. The kinetics of the process followed pseudo-second order (R2 = 0.9723). According to the promising results of the research, the efficiency of dye purification using a magnetic field has increased by about three times compared to the state without this factor. It can be suggested that this system be used as a wastewater treatment process for the textile industry to reduce the toxicity of wastewater and total organic carbon (TOC).
