- Abstract
In the current paper, we investigated the electrochemical degradation of some pharmaceuticals, including an antioxidant (vitamin E), anti-coronavirus and anti-skin diseases and supplements (vitamin B1 or thiamin HCL), anti-inflammatories (caffeine, ibuprofen, acetaminophen), and antidepressants antipsychotic medications (quetiapine fumarate). For this purpose, we employed an advanced electrochemical oxidation process using Ti/nano SnO2-α-Fe2O3 electrode by Na2SO4 or NaCl as a supporting electrolyte. We also evaluated the effects of pH and supporting electrolytes. On the degradation of pharmaceuticals and optimized the process. Results showed that the best conditions for supporting electrolytes were a pH of 7 for Na2SO4 or NaCl with a concentration of 1 g/L. Under optimum conditions, we achieved about 100% efficiency in the removal of pharmaceuticals. The total organic carbon (TOC) removal of 98.57% and 99.37% were also obtained, after 270 min of treatment with Na2SO4 and NaCl, respectively. In addition, in the same condition, the removal efficiency of pharmaceuticals after 150 min, was about 80% and TOC removal was equal to 90.21% and 80.74% with Na2SO4 and NaCl, respectively. It was shown that NaCl was stronger than Na2SO4 stronger Ti/nano SnO2-α-Fe2O3 electrode is applicable for the electrochemical treatment of pharmaceutical pollutants simultaneously.
