【摘要】 研究了风化煤对磷矿酸解反应体系中Ca2+、Fe3+、Al3+及H2PO4-的吸附特性。实验表明:风化煤吸附上述4种离子从易到难的顺序及最大吸附量从大到小的顺序均为:Fe3+、Ca2+、Al3+、H2PO4-;吸附等温方程均符合Lang-muir方程,且相关性显著。为探讨风化煤对磷矿转化率的影响和生产生态型磷肥提供了理论基础。更多还原

【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.更多还原
