Removal of Paracetamol from Pharmaceutical Waste Water by using UV/TiO2 and UV/ZnO2

Pharmaceutical waste is one of the major complex and toxic industrial wastes. Pharmaceutical industry produces a wide variety of products. This industry uses both inorganic and organic as raw materials the latter being either of synthetic or of vegetable and animal origin. Antibiotics and vitamins are produced by fermentation of fairly complex nutrient solutions of organic matter and inorganic salts by fungi or bacteria. Photocatalytic degradation might be facilitated by using semiconductor ZnO and TiO2 which is act to increase the surface area of paracetamol solution to exposed UV light which resulted increase photocatalytic degradation efficiency. The effect of contact time on % reduction of paracetamol using UV/TiO2 process. The experimental analysis carried out for 5 ppm and 10 ppm solutions. For 5 ppm solution at contact time 30, 60, 90, 120 and 150 mins. The % reduction for paracetamol drugs are 40, 57, 68, 73 and 80 resp. using UV/TiO2 process. For 10 ppm solution at contact time 30, 60, 90, 120 and 150 mins. The % reduction for paracetamol drugs are 29, 50, 64,69 and 72.5 resp. using UV/TiO2 process. As per analysis its clear that the % reduction increase with increase in contact time. The max. reduction shown at 120-150 mins. For 5 and 10 ppm max. reduction at 150 mins. can use as optimum time. The effect of contact time on % reduction of paracetamol using UV/ZnO process. The experimental analysis carried out for 5 ppm and 10 ppm solutions. For 5 ppm solution at contact time 30, 60, 90, 120 and 150 mins. The % reduction for paracetamol drugs are 30, 50, 62.5, 71.5 and 77 resp. using UV/ZnO process. For 10 ppm solution at contact time 30, 60, 90, 120 and 150 mins. The % reduction for paracetamol drugs are 25, 42, 57.5 and 69 resp. using UV/ZnO process. As per analysis it’s clear that the % reduction increase with increase in contact time. The max. reduction shown at 120-150 mins. For 5 and 10 ppm max. reduction at 150 mins. can use as optimum time.
