This paper studies the effects of reaction time, temperature, initial concentration of phosphate, pH and organic matter concentration on the adsorbent of briquette ash to phosphate. The results indicate that the briquette ash shows many cavities. The isothermal adsorption process of phosphate on briquette ash can be fitted by Langmuir equations with high correlation coefficient, the maximal adsorption amount is 1250mg·kg-1 according to Langmuir equations. The adsorption amount increases as pH increases in the condition of acidity but decrease in alkalescency, the small molecule organic could reatrain the adsorption of phosphate but strengthen the release of saturation phosphate of briquette ash. The adsorption can be influenced by the adsorbent amount, the unit adsorption amount increases and then decreases slowly.
