摘要
选用D564树脂对某地下卤水中微量硼进行离子交换的分离提取研究。结果表明:D564树脂对硼具有良好的选择吸附性能,饱和容量为8.5 mg/mL,工作容量为5.4 mg/mL;硼的平均吸附率为97.9%,解吸率为100%,洗脱液中硼浓度平均为1 989 mg/L,硼浓度富集了11.8倍,有效地实现了硼的分离与富集,有助于卤水中微量硼的综合利用。
Extraction of trace boron from underground brine by ion exchange using D564 resin was researched. The result shows that： D564 resin has good property of boron adsorption. The saturated capacity is 8.5 mg/mL and the operating capacity is 5.4 mg/mL. The average absorption efficiency of boron is 97.9% , and the desorption efficiency is 100%. The average concentration of boron in the eluent is 1 989 mg/L, which is enriched to 11.8 times. Boron is separated and rich effectively. It is contributed to the comprehensive utilization of trace boron in the underground brine.
