【摘要】 以300W高压汞灯为光源,研究了AgCl对染料废水进行光催化氧化的可行性,以及溶液初始pH值、催化剂的投加量和光照时间等因素对光降解反应的影响。结果表明,在实验条件下,AgCl对活性艳红K-2BP染料有明显的降解效果。AgCl在光照条件下使有机物分解,酸性条件比碱性条件有利于活性艳红的降解,当催化剂用量为0.5mmol/L时,10min光照,染料废水降解率达69.9%。更多还原

【Abstract】 300 W high-pressure mercury lamp was used as the light source. To study the feasibility of dyeing wastewater treatment, the influences of the initial pH value of solution, the amount of catalyst, and illumination time to the photodegradation were also studied. Results showed, under experimental conditions, that AgCl had marked degration effect for reactive red K-2BP. AgCl make organic matter resolve under the terms in illumination and the degradation effect on acidic condition was better than that on basic condition and catalyst amount is 0.5 mmol/L,decolor efficiency of wastewater is 69.9 % in 10min of irradiation.更多还原
