摘要：

研究了H-103大孔吸附树脂处理苯甲酸废水的最适合的工艺条件。在苯甲酸质量浓度为3 000 mg/L时，最佳吸附条件为：温度为室温,pH=2，动态吸附流速为7BV/h；最佳洗脱条件为：体积分数为95%的乙醇用量为80 mL。静态吸附后苯甲酸的去除率为78.7%，动态吸附后其去除率为99.98%，树脂的反复使用性能良好。

Abstract:

The best conditions of treating benzoic acid wastewater with H-103 adsorptions resin have been studied.The results show that when the benzoic acid mass concentration is 3 000 mg/L，the optimum adsorption conditions are at room temperature，pH=2，and the dynamic adsorption velocity of flow is 7 BV/h. The most desorption condition is that the dosage of 95% ethanol should be 80 mL. After static adsorption experiment，the removal rate of benzoic acid is 78.7%，but after dynamic adsorption experiment，its removal rate is 99.98%. The reusable capability of the macroporous resin is good.

Key words: macroporous resin；benzoic acid, adsorption conditions, desorption conditions
