Laboratory investigation demonstrates photoelectrocatalytic degradation of hazardous hair dyes using tungsten trioxide anodes, highlighting an effective method for wastewater treatment.
The indiscriminate use of hair dyes has attracted great deal of attention due to its toxicological and mutagenic aspects demonstrated by some of these substances. Thus, the effluent from beauty salons and domestic sewages if not properly treated can reach water treatment plants and water sources, enhancing human health and environmental protection concern. This work explores the application of photoelectrocatalytic process on Basic Brown 16 and Basic Blue 99 degradation as model of basic hair dyes pollutants. W/WO
