Abstract

Pharmaceutical
effluents are the waste generated by pharmaceutical industry during the process
of drug manufacturing waste and are characteristically high in organic content.
Over the past few years, pharmaceutical waste is considered as an emerging
environmental problem due to its continuous input and persistence in the
aquatic ecosystem even at low concentration. Hence, in the present study, the
treatment of pharmaceutical effluent is evaluated using chemical method in
order to Chemical Oxidation Demand (COD) Various operational parameters like
the effect of pH, concentration of H₂O₂, Fe^2+,
and dosages of TiO₂ and nano TiO₂ were all investigated
in UV mediated. Maximum COD reduction with present of Ultraviolet at pH3 was
44% and hydrogen peroxide (UV/H₂O₂) was 68% at 180 min
with 30 ppm concentration and in combination of 30ppm of H₂O₂
and 3ppmFenton with present of UV maximum COD reduction was 88% at 180, 69% was
observed at 0.3g of TiO₂ and in combination of Nano TiO₂
maximum reduction was 97% and found Nano TiO₂ to be more efficient
compared to others.
