Abstract	In this study gas concrete waste was used to remove phosphate from aqueous solutions. The influence of suspension pH, temperature, mixing rate, and gas concrete dosage on phosphate removal was investigated by conduction a series of batch adsorption experiments. In addition, the yield and mechanisms of phosphate removal were explained on the basis of the results of X-ray spectroscopy, measurements of zeta potential of particles, both values of BET-N(2) specific surface area, and images of scanning electron microscopy (SEM) of the particles before and after adsorption. Phosphate removal in excess of 99% was obtained in this study and it was concluded that wastes of gas concrete are an efficient adsorbent for the removal of phosphate. The removal of phosphate predominantly takes place by precipitation mechanism and the weak physical interactions between the surface of adsorbent and the metallic salts of phosphate.
