地质特种水泥对模拟含锶废液的静态吸附性能研究

Static Adsorption of Simulated Strontium-containing Wastewater by Special Geological Cement

选用地质特种水泥原料粉末作为吸附剂,研究了吸附剂对含锶溶液的静态吸附规律。结果表明,静态吸附平衡的最大吸附率为47.91%;最佳吸附时间为1.6 d;在碱性条件下地质特种水泥吸附效果最佳;吸附速率按照与吸附驱动力的平方呈正比关系进行演变;地质特种水泥对锶离子的吸附为单分子层吸附。

Static adsorption of Strontium solution was studied in this experiment,with raw material powder ofspecial geological cement used as the adsorbent . The results show that the maximum adsorption rate at equilibrium is 47.91%,the optimum adsorption time is 1.6 d,with the best performance of the cement under alkaline condition. The adsorption rate is proportional to the square of adsorption driving force. The adsorption ofstrontium ions by special geological cement is monolayer adsorption.
