摘要/Abstract

摘要： 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。

Abstract: Static adsorption of Strontium solution was studied in this experiment, with raw material powder of special geologicalcement used as the adsorbent. The results show that the maximum adsorption rateat equilibrium is 47.91%, the optimum adsorption time is 1.6 d, with the best performance of the cement under alkaline condition. The adsorption rate is proportional to the square of adsorption driving force. The adsorption of strontium ions by special geological cement is monolayer adsorption.

Key words: Wastewater containing strontium, Special cement, Static adsorption
