Abstract

Discharges from pharmaceutical sectors into water bodies are major environmental issue as most of them are persistent in nature and causes endocrine disruption. Treatment processes presently undertaken are not effective in complete removal of these contaminants. Removal study of ibuprofen has been undertaken by adsorption and nanofiltration membrane whereas little knowledge of atenolol separation by membrane has been reported. Ceramic ultrafiltration membrane developed from green synthesized zinc oxide nanoparticles (ZnO NPs) was employed in this present study for removal of atenolol and ibuprofen drugs from synthetic solution. About 96% and 99% removal of atenolol and ibuprofen respectively was obtained by single step ultrafiltration process. OF membrane developed had surface area of 21.503 m(2)/g and pore diameter of 39.8 angstrom. X-ray diffraction study of unsupported membrane showed pure phase crystalline zinc oxide particles. The effect of different parameters viz., TMP (Transmembrane pressure), time, feed concentration etc. on membrane filtration efficiency was analyzed by RSM (Response Surface Methodology). Germination studies on Vigna mungo was performed using untreated atenolol and ibuprofen solutions and membrane treated permeate to assess the membrane efficiency of producing clean water suitable for reuse. The study revealed higher germination rate in presence of ibuprofen solution but lower germination for atenolol solution. Protein content on the other hand were highly affected in both ibuprofen and atenolol solution. Seeds germinated in membrane permeate showed better germination rate and protein content and comparable to that of control.
