目前广泛应用测定酚的方法是Emerson改进的4-氨基安替比林比色法,此法主要缺点是不能测定对位酚。本文采用流动注射电流分析技术研究了微量酚类化合物的测定,并进行实际水样分析。本方法可测定ppb—ppm的酚,灵敏度与文献相当,但操作简单,样品用量少,体现了流动注射分析的快速特点,每小时可测80个样品。实验部分仪器:流动注射分析仪由蠕动泵、旋转进样阀、混合管、检测器、放大器、记录仪几部 At present, the widely used method for the determination of phenol is Emerson’s improved 4-aminoantipyrine colorimetric method. The main disadvantage of this method is that phenol can not be measured. In this paper, the determination of trace phenolic compounds was studied by flow injection current analysis and the actual water samples were analyzed. The method can measure ppb-ppm of phenol, the sensitivity is comparable with the literature, but the operation is simple and the amount of sample used is small, which reflects the rapid characteristic of flow injection analysis. The method can measure 80 samples per hour. Experimental equipment: flow injection analyzer consists of peristaltic pump, rotary injection valve, mixing tube, detector, amplifier, recorder several
