Abstract
Heavy metal ions such as Zinc, Cadmium, Lead, Copper and Nickel are menacing to both human life and the environment. In the present effort, investigation aimed to enhance the removal of Pb(II) from waste water by ultrasound promoted adsorption using Methyltrio ctylammonium Chloride modified Silica gel was carried out. The synthesized materials were characterized by Fourier Transform Infrared (FTIR) spectroscopy and X-Ray Diffraction (XRD). To analyse the adsorption of Lead ions from aqueous solutions batch adsorption studies were carried out. The factors which influence the % adsorption of Pb(II) on ILSilica gel such as adsorbent dose, contact time, pH value of Pb(II) solution, temperature and adsorbate concentration had been investigated. Adsorption of Pb(II) on the IL-Silica gel was correlated well with the Langmuir model. It has been established that IL-Silica gel has the aptitude to be used for large scale separation of Lead from wastewater under ultrasound irradiations.
