Abstract In this study, Yb/KIT-6 was used as an adsorbent for Phosphorus Removal from wastewater and aqueous solutions for the first time. The mesoporous silicate, KIT-6, was synthesised via a hydrothermal method. The Yb/KIT-6 adsorbent, containing Yb/Si with a molar ratio ranging from 0.05 to 0.5 (mol of Yb/ mol of Si), was prepared by wet impregnation. Phosphate adsorption was detected by measuring the aqueous concentration of phosphate utilising ultraviolet-visible (UV-Vis) spectroscopy before and after removal. The materials studied were characterised before and after phosphate removal tests using N2 adsorption/desorption, low-angle XRD (SAXS), high-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The maximum adsorption capacity of the modified silicate material was 20.85 mg P/g adsorbent. The effect of pH and coexistence of other anions (chloride, sulphate, nitrate, and bicarbonate) on phosphate removal was examined. Except for bicarbonate, the anions investigated had no significant effect on phosphate adsorption, and hence this material shows promise for removal of phosphorus from wastewater.
