摘要: 多环芳烃化合物因广泛使用，在环境水体中经常检出，故急需研究其去除技术。本实验以过碳酸钠(SPC)构建光助均相氧化体系，以萘为模型化合物，以高效液相色谱法(HPLC)为实验方法，对ZnO + UV、ZnO + 过碳酸钠、UV + 过碳酸钠、UV + ZnO + 过碳酸钠四个降解系统进行了筛选。实验得到过碳酸钠 + UV体系为四者中最佳。采用单因素和正交实验对该体系的降解能力进行优化。通过对过碳酸钠投加量、萘母液浓度、UV照射时间以及pH对萘降解效率影响的研究，得出过碳酸钠 + UV体系中最佳反应条件为：过碳酸钠投加量0.267 g，萘母液浓度0.5 mg/mL，UV照射时间30 min，pH = 6.0。经验证，在此条件下，萘的降解率达到最高。实验表明，UV强化过碳酸钠催化萘降解体系可以有效降解水中的萘，并且降解率较高。此外，该方法较好地克服了当下化学降解法对环境的污染困境，有广阔的发展前景。
Abstract: Because PAHs are widely used and often detected in the aquatic environment, it is urgent to study the removal high-efficiency methods of it. In this study, four degradation systems were screened by using sodium percarbonate (SPC) to construct a photo-assisted homogeneous oxidation system, naphthalene as a model compound, and HPLC as an experimental method. The optimal sodium percarbonate with UV system was obtained. The system was optimized by complete randomized design and orthogonal experimental design. The effects of sodium percarbonate dosage, concen-tration of naphthalene mother liquor, UV irradiation time and pH on the degradation efficiency of naphthalene were investigated. The optimal reaction conditions were as follows: sodium percarbonate dosage of 0.267 g, concentration of naphthalene mother liquor of 0.5 mg/mL, UV ir-radiation time of 30 min, pH = 6.0. Under these conditions, the degradation rate of naphthalene was highest, which showed that the UV enhanced sodium percarbonate catalyzed naphthalene degradation system could effectively degrade naphthalene in water, and the degradation rate was higher. In addition, this method has better overcome the current environmental pollution dilemma of chemical degradation methods, and has broad development prospects.
