| Abstract: | For a theory analysis on the conversion ratio of phosphate rock in ecological phosphate fertilizer production,the adsorption characteristics of weathered coal on Ca2 ,Fe3 ,Al3 and H2PO4-in acid decomposing phosphate rock system were discussed.The results showed that the sequences both adsorption from easy to difficult and the maximum adsorption values from large to little were ranked in Fe3 ,Ca2 ,Al3 and H2PO4-,and the adsorption in accordance with Langmuir equations in significant correlations. |
