“…Some of the different types of synthetic dyes that are available includes: acidic, reactive, basic, disperse, and azo etc. Most of these dyes have complex molecular structure, which results in them to have low biodegradability and thus possess a threat to the environment [2]. During the year 2010, it has been estimated that more than 10,000 types of pigments and synthetic dyes are used in large quantities in numerous industries like textile, leather, food and cosmetics etc.…”

The homogeneous advanced oxidation process of ultraviolet (UV) radiation in presence of hydrogen peroxide (H 2 O 2 ) was utilized to degrade Alizarin Yellow R, one of the most commonly used azo dyes in the textile industry. In this study, the effects of initial H 2 O 2 concentration, initial dye concentration, initial pH, and temperature were examined to determine the optimum conditions for maximum degradation. Complete degradation was achieved within 1 h, for all the experimental conditions studied in the present work. The Box-Behnken response surface methodology (RSM) was used for optimizing the variables of the degradation process. Based on the estimated optimum conditions, 92.7% of degradation was achieved. The degradation process was found to follow first order kinetics. The estimated rate constants, along with the optimized conditions will be of useful for the design and scale up of the combined UV/H 2 O 2 process for the said purpose.

Photocatalytic degradation of indole in UV/TiO2: optimization and modelling using the response surface methodology (RSM)

The aim of our research is to apply experimental design methodology to the optimization of photocatalytic degradation of indole present in wastewater. Heterogeneous photocatalysis for the oxidation of organic biorecalcitrant pollutants in water is an environmental promising method. We used the response surface methodology (RSM) for the modelization and optimization of the photodegradation of indole in the presence of titanium dioxide. The effect of indole concentration, UV intensity and stirring speed on the yield of indole degradation was determined. According to the mathematic optimization of the process, the optimum point when 100% of degradation is achieved is given by the following values: UV intensity = 250 W/m 2 , stirring speed = 536.36 tr/min and initial indole concentration = 10.10 mg/l.
