SYNTHESIS OF ISOXAZOLE DRIVATIVES ON DISINFECTION OF FICAL COLIFORM BACTERIA

Background and Aim:The prepared isoxazole derivatives constitute the base of some drugs. Coliforms are the most important index of water and wastewater pollution. The main objective of this research was the study of disinfection of coliform bacteria as wastewater using synthesized aromatic isoxazole derivatives.Methods:The isoxazole derivatives were synthesized by poly(N-bromo-N-ethyl-benzene-1,3-disulfonamide) [PBBS] and N,N,N ,N -tetrabromobenzene-1,3-disulfonamide [TBBDA]. Synthesized aromatic isoxazole derivatives were added to certain amounts of wastewater. Along with disinfection, fecal coliform was detected in untreated and disinfected wastewater.Results:The results showed that in presence of aromatic isoxazole derivatives, fecal coliform was disinfected more effectively. Maximum removal was observed in aromatic isoxazole substituted derivatives with a halogen substituent. Removal of 100% was observed at some derivatives even at 10 min.Conclusion:Aromatic Isoxazole derivatives may be effectively applied for wastewater disinfection. because of advantages of reaction condition at room temprature and using of water as solvent, this process is a green reaction.
