Abstract
Mesoporous silica nanoparticles are one of the most promising adsorbents for metal ions due to their ultrahigh surface area, outsized pore size, and miscellaneous composition. However, their applications remain limited as a frail ion exchanger for anion adsorption due to the existence of silanol groups on the surface in order to overcome these drawbacks, hybrid organic–inorganic silica material with high specific surface area, highly adsorptive capacity, and good chemical and thermal stability was prepared. We report here a facile method for the preparation of newly amine functionalized silica-pectin hybrid material. To better understand about the surface modification of the silica gels, the analysis of materials’ surfaces was conducted using Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), transmission electron microscopy (TEM). The important yardstick for experimental analysis is the comparative phosphate anion removal efficiency of the composite material in artificial wastewater and how the trend of phosphate anion changes with the effect of temperature, the influence time, the effect of pH, the significance of dose of adsorbent and initial anion concentration in the process of the selective removal of phosphate anion.
