- Furthermore, samples, as catalysis, were used to degrade simulation dye effluents, such as solutions of Acid Red G, Direct Bordeaux, Direct Red and Methylene Blue. 同时以酸性红G、直接枣红和直接大红(直接染料)及亚甲基蓝为对象模拟染料废水进行催化降解实验。
- After UV-light irradiation for 20min, 60% of the acid red G was decoloured, which was higher than 20% of the Degussa P25 and K_4Nb_6O_17 obtained by solid-state reaction. 光催化降解20min后，水热法合成的K_4Nb_6O_17的脱色率已达60%25，而高温固相法的K_4Nb_6O_17和Degussa P25的脱色率都仅为20%25。
- The results showed that the decolouration of acid red G mainly owe to the photocatalytic degradation of Co-doped K2Nb4O11, but not to the adsorption on it. 研究表明，酸性红G的降解主要是含Co的K2Nb4O11对其的光催化降解，而并非吸附作用，但酸性红G自身也存在少量的光降解。
- In this paper, K2Nb4O11 and Co-doped K2Nb4O11 were prepared by solid-phase reaction and their photocatalytic activities were evaluated by the photodegradation of acid red G on the catalysts. 本文采用固相法合成了K2Nb4O11 和掺Co的K2Nb4O11，研究了Co掺杂对K2Nb4O11降解酸性红G溶液的光催化活性的影响。
- The results show that the absorbance of methyl orange decreases, and that of acid red G solution increases when the power of the ultrasound is relatively high with little treatment capacity. 结果表明：超声会对染液的吸光度产生影响，甲基橙染料的吸光度有所下降，而采用较大功率超声处理少量酸性大红G溶液时，其吸光度增大。
