摘要
研究了用吸光光度法间接测定痕量苯酚的方法。在 KBrO_3和KBr溶液中,以淀粉-碘化钾为显色剂,最大吸收波长为590nm,线性范围为0.1～2.0mg/L,测定值的相对标准偏差为2.36％,平均回收率为101％。该方法应用于测定废水中苯酚,结果满意。
A method of determinating trace phenol by indirect analysis with spectrophotometry is discussed in this paper. The maximun absorbance is at 590 nm when starch idide is used as color reagent in KBrO3-KBr solution. The amount of phenol is in the range of 0. 1-2. 0 mg. L-1 the deviation is 2. 36 %;the average recovery is 101%. The method has been used to determine thephenol in sewage and the results are satifacory.
