Abstract

Eriochrome Black-T (EBT) is a commonly used textile dye. It is a harmful organic molecule and is also present in textile effluent. The photocatalytic degradation has been studied using MBIR Dowex-1×8 as the photocatalyst. Some parameters such as pH, light intensity, the amount of photocatalyst and initial dye concentration were also studied. At room temperature at pH 7.5, the optimal degradation of Eriochrome Black-T dye (30 mg/L) was observed in about 210 minutes and the photo catalyst load was 2.0 gm. The kinetic study related to the photocatalytic degradation of EBT followed first order kinetics where the rate constant is 2.11x10-2 min-1. This catalyst can degrade dye molecules and can recover transparent water from coloured textile effluent in few hours of treatment.
固定化Dowex-1x8光催化降解铬黑- t染料
铬黑- t (EBT)是一种常用的纺织染料。它是一种有害的有机分子,也存在于纺织废水中。以MBIR Dowex-1×8为光催化剂进行了光催化降解研究。并对pH、光强、光催化剂用量、初始染料浓度等参数进行了研究。在室温pH 7.5条件下,30 mg/L Eriochrome Black-T染料的最佳降解时间为210 min,光催化剂负载为2.0 gm。光催化降解EBT的动力学研究符合一级动力学,速率常数为2.11x10-2 min-1。该催化剂能降解染料分子,并能在几个小时内从有色纺织品废水中回收透明水。
