通过气体电晕放电的直接接触，检查了溶解到水中的几种无机污染物对水性有机化合物分解的影响。结果发现，向水中添加0.01 mol l−1NaOH显着促进了水溶液苯酚的分解，而添加相同浓度的HCl则抑制了分解速率。由于已知苯酚在反应器中分解过程中转化为稳定的乙酸，因此考察了NaOH、HCl、H3PO4和NaCl对乙酸降解的影响。结果，溶解的 Cl− 抑制了其分解效率。研究还发现，将 pH 值提高到高于 11 后，分解速率会显着提高。
The influence of dissolved several inorganic contaminants into water was examined on the decomposition of aqueous organic compounds by direct contact of gas corona discharge. It was found that addition of 0.01 mol l−1NaOH into water significantly improves the decomposition of aqueous phenol while the addition of HCl of the same concentration inhibits the decomposition rate. As it is known that phenol is converted to stable acetic acid during the decomposition process in the reactor, the influence of NaOH, HCl, H3PO4and NaCl was examined on the degradation of acetic acid. As a result, dissolved Cl−inhibits its decomposition efficiency. It is also found that this decomposition rate is significantly improved by raised pH which is higher than 11.
