摘要

本文报道了用不同的半导体氧化物混合物作为催化剂,光催化降解偶氮染料酸黑52。实验系统由间歇式反应器组成,其中偶氮染料、半导体氧化物和过氧化氢的浓度分别为0.1 mM、100 mg/L和65.2 mM。用磁力搅拌器将混合物均质,并将pH调至3.0。初始体积为500 mL。将白光灯(127 V, 60 Hz, 362 mA, 60 W, 60 lm/W)同轴放置于反应器并打开以激活催化剂。每隔30分钟取样品测量吸光度,使用HACH DR3900分光光度计。经过180分钟的处理,锰氧化物和铁氧化物的混合物对偶氮染料的降解效果最好,达到60%。这项工作的目的是利用可见光激发的催化剂将污染物完全转化为二氧化碳,以避免其对环境和人类健康的不利影响。

Tratamiento fotocatalítico de una disolución acuosa de azocolorante Negro Ácido 52 utilizando como catalizador diferentes mezclas de óxidos semiconductores
In this study, the photocatalytic degradation of azo dye Acid Black 52 using different mixtures of semiconductor oxides as a catalyst is reported. The experimental system consisted of a Batch reactor in which the azo dye, the semiconductor oxides and the hydrogen peroxide were mixed, whose concentrations were 0.1 mM, 100 mg/L and 65.2 mM, respectively. The mixture was homogenized by a magnetic stirrer and the pH was adjusted to 3.0. The initial volume was 500 mL. A white light lamp (127 V, 60 Hz, 362 mA, 60 W, 60 lm/W) was placed coaxial to the reactor and turned on to activate the catalyst. Samples were taken every 30 minutes to measure the absorbance, for this purpose a HACH DR3900 spectrophotometer was used. After 180 minutes of treatment, the best result, 60% degradation of the azo dye, was obtained with the mixture manganese oxides-iron oxides. The purpose of this work was to completely transform the pollutant into carbon dioxide, to avoid its adverse effects on the environment and human health, using catalysts excited with visible radiation.
