Abstract

Nowadays the requirement for clean water in human population is growing day by day. The different factories and industries like pharmaceutical, textile, food processing, leather, printing and chemical industries are the major cause of water contamination by adding an organic dyes. The aim of present study is to synthesize the green nanoparticles for the purification waste water. The TiO2 nanoparticles were prepared using crude extract of pharmaceutical important local plant Acacia nilotica. The synthesized TiO2 nanoparticles were characterized using different analytical approaches. The TiO2 nanoparticles initially were confirmed by color change and later by UV-spectroscopy. The Fourier transforms infrared (FTIR) were also performed. The size and shape of TiO2 nanoparticles were assessed by using field emission scanning electron microscope (FESEM). The Energy Dispersive X-ray spectrometric analysis (EDS) was performed to measure the elements concentrations. Dye removing potential of prepared TiO2 nanoparticles were performed using methylene blue induced dye mixture. The result showed that the synthesized TiO2 nanoparticles were round and spherical in shape ranging from 50-120nm with average of 60nm. EDS confirmed the TiO2 presence in nanoparticles. The synthesized TiO2 nanoparticles showed 75% dye removing capacity after 2 hours of exposure. In conclusion, our rapidly green synthesized TiO2 nanoparticles were highly effective for removing dye from water, therefore these TiO2 nanoparticles can be used as best source for waste water treatment with minimum cast for removing dyes from waste water
