Using of titanate nanowires in removal of lead ions from waste water and its biological activity

Abstract

Abstract Lead is a one of the most hazardous heavy metals that requires a good sorbent in order to be removed from the decontaminated water. Herein, titanium dioxide nanowires were hydrothermally synthesized from titanium dioxide nanoparticles. The nanowires obtained were characterized by transmission electron microscope (TEM), Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), and Surface area (BET). The nanowires produced were utilized as an effective sorbent for lead ions from synthetic waste water. The optimized conditions in terms of pH, concentration and time effects have been intensively investigated. While recovery, titanium dioxide nanowires showed better workability for lead elimination after the second run. The antimicrobial activity of the prepared nanowires was also discussed against deleterious microbes. Thus, titanium dioxide nanowires are considered as a green and an alternative candidate for water remediation purposes thanks to the intrinsic duel functions, adsorbent and antimicrobial agent.
