摘要
本文报道了以０．１ｍｏｌ／Ｌ氢氧化钠为稀释液，用紫外光谱在２３５ｎｍ波长处检测废水中酚的含量．结果与以Ｋ３〔Ｆｅ（ＣＮ）６〕为氧化剂的的４－氨基安替比林分光光度法相比，本方法具有更高的灵敏度（摩尔吸光系数ε＝１．７×１０－５Ｌ／（ｍｏｌ·ｃｍ）．是氨基安替比林分光光度法灵敏度的２倍）．酚氢氧化钠溶液浓度在０．８～６．４μｇ／ｍＬ范围内与吸光度呈良好的线性关系（ｒ＝０．９９９１）；回收率为９９．７５～１０１．８８％，相对标准偏差ＲＳＤ≤０．１２％（ｎ＝９），证明方法的准确度与精密度令人满意．该法不需要特殊试剂，所以简便快速，同时应用微机对数据进行了最小二乘法处理和回归分析及结果计算，避免了通过标准曲线计算“废水”
In this paper, described 0.1mol/L sodium hydroxide as diluent in the determination of phenol in polluted water spectrophotometrically . It was contrasted with the usual spectrophotometrical reagent 4-amino antipyrine, the results showed NaOH diluent the sensitivity twice higher. The calibration curve obeys Beer's Law over the range 0.8-6.4μg/mL of the phenol sodium hydroxide solution (r=0.9991). The recovery is 99.75-101.88% and the coefficient of variation is 0.12% (n=9). The method needn't add any specific reagent. It is a simple and convenient method of all.
