利用离子交换树脂吸附黄水中的有机酸，从5种树暗中筛选出了对黄水中的己酸、乙酸、乳酸有较好吸附能力的树脂A。结果表明，树脂A对黄水的静态吸附能力最强，达到178．71mg／g；动态吸附过程中，树脂A对黄水中的色素有一定的吸附；但并不影响其对黄水中有机酸的吸附。对洗脱液的气相色谱检测表明，洗脱液中己酸、乙酸、乳酸的含量均衡，洗脱率高。

Ion exchange resins were used to absorb organic acids from yellow water, in this study, five kinds of ion exchange resins were used and resin A had better performance in the absorption of acetic acid, caproic acid and lactic acid. The absorption capacity of resin A was highest up to 178.71 mg. g^-1 under static state. Under dynamic state, resin A would absorb certain yellow water pigment, which would not influence its absorp- tion of organic acids. GC analysis ofeluent indicated that the content of caproic acid, acetic acid, and lactic acid in the eluent kept equilibrium and their elution rate was high.
