Optimized, simple and selective analytical tool for determination of carcinogenic aniline in wastewater

Here, we explored a low-cost, rapid, sensitive, and selective practical approach to manifest carcinogenic anilines by using oxone as an oxidant to mitigate its presence in wastewater. The calibration curves for OAP & PAP indicate reasonable sensitivity, percent recovery & correlation in the range 2.18–9.28 μg/mL. The Sandell's sensitivity for OAP & PAP was found to be 0.010–0.018 & 0.009–0.018 μg/mL, respectively. The range of correlation coefficient 0.979 to 0.998 shows the involvement of high precision and perfect correlation of the data. Values of coefficient of determination (r2) denote the change in absorbance or (dA/dt)i or kobs by 95.8–99.6%. The percent recovery was found to be 98.05–99.91% for six parallel determinations. Furthermore, we also analyzed some wastewater samples to further validate the proposed method. The reproducible results, good percent recovery, and reasonable sensitivity proposed a feasible approach for the estimation of aminophenol in wastewater.
