Spectrophotometer Method for Removal of Paraben by Using UV/H2O2 Process

Parabens are esters of para-hydroxybenzoic acid, with an alkyl (methyl, ethyl, propyl, or butyl) or benzyl group. They are mainly used as preservatives in foodstuffs, cosmetics, and pharmaceutical drugs. Parabens are present at low concentration levels in effluents of the wastewater treatment plant. These parabens have continuously entered the environment and cause serious threats to aquatic and humans. So, the elimination of parabens is important in wastewater. The study aims to remove the paraben from an aqueous solution using the UV/H2O2 process. The parameters vary such as pH, H2O2, pollutant concentration, and time. The simple, rapid and sensitive UV spectroscopy method was used for the determination of paraben. Paraben was observed maximum at the absorbance of 254 nm. The results show that the maximum removal will be observed at the optimum conditions. The removal efficiency of paraben will be noted and reported in the study.
