[Display omitted] •Granulation followed by ferric loading had the best phosphate adsorption capacity.•The phosphate adsorption capacity was increased from 0 to 0.963mg/g.•Both granulation and ferric oxides loading obviously increased the surface areas.•Pseudo-first order model is allowable to estima...
