Abstract: Simple, accurate, fast, and economical method for removal of OTC in pharma wastewater has been developed. The procedure is based on the adsorption mechanism which leads to the spectrophotometry. Bentone -34 clay is used as an adsorbent for removal of OTC. 0.1 N HCl was used as a mobile phase. The elute was determined spectroscopically, with a Cecil CE 2041 UV/VIS spectrophotometer, in a 1-cm cuvette cell at wavelength range 190−1100 nm, with resolution 0.5 nm. The linear calibration curve was established in the concentration range 0.214-1.070 mg/mL of OTC. From the analyzed data the following results for parameters were obtained linearity correlation R2 > 0.9984), accuracy (Recovery = 91−98%), sensitivity (LOD = 42.3 mg/mL; LOQ = 48.3 mg/mL), and precision (RSD ≥ 2.0%) in the respective linear concentration ranges. The method is successfully applied for the removal of OTC as the tested sample improves ICH parameters like accuracy, sensitivity, precision.
