Advanced Oxidation Processes against p-Amino Benzoic Acid in Groundwater Samples

Organic waste from four groundwater sources near an oil refinery in Vadodara, India, was analysed using a spectrophotometer to identify phenolic chemicals. The average concentration of phenolic compounds in these samples was 0.38 mg L -1 using the Folin technique. It was discovered that p-aminobenzoic acid was the most common form of phenolic contamination in the samples. The breakdown of these compounds in soil and the activity of bacteria, which can lead to the construction of structures more resistant to different kinds of oxidation, is the focus of current environmental research on removing p-aminobenzoic acid from real water samples. Using a 2 mg L -1 laboratory sample of different aromatic chemicals to assess the efficiency of AOP in eliminating p-aminobenzoic acid from the groundwater sources under investigation is necessary. Actual samples must be analysed for O 3 /UV and O 3 /UV/H 2 O 2 in each of these methods (5000 mg L -1 H 2 O 2 , 15 min UV C , 2 mg L -1 O 3 , 15 min UV C ). For actual samples, the average removal rate was 79.52 percent, whereas the average removal rate for lab samples was just 79.52%. The O 3 /UV approach appears to be the most cost-effective, simplest to deploy, and safest solution for large-scale projects, according to the research.
