Synthetic 13X zeolite was used to conduct static adsorption experiments on lysine. The effects of pH, temperature, time and zeolite dosage on adsorption rate were experimentally investigated. In the experiments, the ratio of adsorption reached a plateau value when the adsorption time was 30 min at the ambient temperature, and the saturation adsorption capacity of 13X zeolite on lysine in wastewater was 51.73 mg·g-1 when pH=pKa1=2.2. The adsorption isotherm for the process was approximately linear, and the ion exchange was probably the major adsorption mechanism. 13X zeolite could be regenerated by saturated NaCl solution without the noticeable loss of capacity. The desorption rate was higher than 95%. Experimental studies indicate that 13X zeolite is suitable for the purification of lysine-bearing wastewater.

用合成的13X沸石对废水中氨基酸(赖氨酸)进行静态吸附实验,研究了pH、温度、吸附时间、沸石用量等对吸附率的影响,结果表明,室温下沸石对赖氨酸的吸附平衡时间为30min,pH=pKa1=2.2时,赖氨酸在沸石上的吸附效果最好,吸附率大于82%,饱和吸附量达51.73mg.g-1。吸附等温线近似呈直线型,表明离子交换机制是沸石吸附氨基酸的主要方式。对已饱和吸附的沸石用饱和氯化钠溶液进行再生实验,赖氨酸的解吸率大于95%,沸石可重复使用。实验研究表明可用13X分子筛处理含氨基酸废水,为实际处理含氨基酸废水提供了可行性依据。
