研究了强碱阴离子交换剂Amberlite IRA-400（Cl - form）在25℃条件下pH（3-11）和不同初始浓度范围（5-25 ppm,120-190 ppm）对磷酸盐吸附的影响。释放氯离子/吸附磷酸盐的比例随pH的增加而增加，随溶液浓度的增加而降低。结果表明，磷酸吸附首先以HPO2−4形式发生，其次是H2PO−4。用Langmuir和质量定律作用方程对数据进行了解释。
Abstract Phosphate sorption on the strong basic anion exchanger Amberlite IRA-400(Cl−form)is studied as a function of pH(3-11)and different initial concentration ranges (5-25 ppm,120-190 ppm)at 25°C. The ratio of chloride released /phosphate sorbed increases with the increase in pH and decrease with the increase in the concentration of the solution. It is suggested that phosphate sorption takes place initially as HPO2− 4 followed by H2PO− 4. The data is explained with the help of Langmuir and mass law action equations.
