Effect of hydrogen peroxide and ferrous ion on the degradation of 2-Aminopyridine
Pharmaceutical compounds 2-Aminopyridine were detected in drinking water, surface water, and groundwater. 2-Aminopyridine is a colourless solid used for manufacturing drugs, sulphapyridine which is extremely poisonous and carcinogenic. Its appearance in drinking water needs prior treatment to dispose of safely. Fenton, Photo-Fenton oxidation processes were carried out to degrade 2-Aminopyridine. Parameters like pH, the dosage of Hydrogen peroxide, and Iron are optimized for the effective degradation of a 2-Aminopyridine compound in water. The effect of the initial concentration (10-80) mg/L of a 2-Aminopyridine pharmaceutical compound on degradation was studied. Drug at initial concentration of 10 mg/L, 40 mg/L and 80 mg/L is 100% degraded in 30 mins,45 mins and 120 mins respectively. Similarly, COD removals of 94.6%, 88.6% and 81% were detected at 10 mg/L, 40 mg/L and 80 mg/L of initial drug dosage. The degradation was enhanced by photo-Fenton oxidation. Both the drug degradation and COD reduction were improved by UV-C-assisted photo-Fenton oxidation processes.
