This paper aims to study the phosphorus adsorbability in water by five types of silicate substrates, namely, zeolite, expanded vermiculite, porcelain sand ceramicite, shale ceramicite, and clay ceramicite, before and after modification. The effect of silicate substrates dosage, adsorption period, pH, and other factors on removal rate of phosphorus was also analyzed. The results indicated that expanded vermiculite before modification had the best phosphorus adsorbability, followed by porcelain sand ceramicite, shale ceramicite, clay ceramicite, and zeolite. The expanded vermiculite modified with magnesium and aluminum salts presented a better effect in phosphorus removal. The best working conditions were found at 10g/L of modifier dosage, pH 5-9, and an oscillation period of 60 mins, which achieved a phosphorus removal rate above 97%.
