摘要
选用无毒性的磷酸三丁酯为流动载体，煤油为膜溶剂的液膜萃取体系，建立了支撑液膜在线萃取富集流动注射荧光光度法测定水中痕量苯酚的新方法。对实验条件进行了优化。方法的检出限为0.4μg／L，线性范围为1-180μg／L。
An on line supported liquid membrane enrichment flow-injection spectrofluorimetric method for detennination of trace phenol in water has been developed. A nonpoisonous cartier, tributyl-phosphate （TBP） dissolved in kero- sene is used in the supported liquid membrane extraction system. Experimental conditions are optimized. Under optimum conditions, the detection limit for phenol is 0.4μg/L, the linear range of the determination is 1-180μg/L. The method has been applied to the determination of trace phenol in river water with satisfactory results.
