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 k_obs 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.
