Synthesis of TiO2 by Hydrolysis/Electrochemical to Reduce Hazardous Disinfecting Materials

Abstract

The TiO2 photo-catalysis can be used for the purpose of disinfectant purpose. In  this  work,  the  TiO2   prepared  by  hydrolysis-electrochemical method  was  used  to produce  disinfectant  to  replace  and  reduse  conventional  material  disinfectant.  The synthesis of TiO2  was occured at constant voltage of 10 V for 2.5 hours under constant stirring  and  room  temperature.  The  product  of  synthesis  was  analysed  by  scanning electron microscopy, energy dispersive X-ray spectrometry, and X-ray diffractometer. The performance of desinfectant was done with inactivation of bacteria E coli in solid media. The phase of TiO2 particle producted shows anatase and rutile phase. The TiO2 resulted from hydrolysis/electrohemical method can be used to reduce HCl for desinfectant. The results of testing disinfectant for inactivation of bacteria E coli in solid media show that disinfectant  from  HCl/TiO2   is  the  most  efective  to  inactivation  of  bateria  E.  coli. Treatment with ultraviolet rays resulted less number of bacteria than sunlight.
