查询词典 wastewater

PMN has a function of oxidation and adsorption under acidic conditions, such as Gentian Purple, Methylene Blue, Conga Red, Rhodamine B and Methyl Orange. PMN can oxidize diversiform dyes (pH＜4. 5). The increasing of concentration on Mn and wastewater UV-Vis spectra after contact can prove it.

PMN在酸性条件下（pH＜4.5）可氧化多种染料，如龙胆紫、亚甲基蓝、刚果红、罗丹明B和甲基橙等，通过测定体系Mn的生成量和模拟废水脱色后的紫外可见吸收曲线可有力证明上述观点。
