【摘要】 提出用多波长线性回归紫外吸光光度法同时测定炼油厂污水中的苯酚和苯胺.方法省去了萃取、蒸馏、显色等步骤,操作简单.对合成水样进行测定,相对标准偏差≤4.57%,相对误差≤±2.3%.对炼油厂水样进行测定并进行加标回收试验,苯酚和苯胶的回收率分别为99.4%～103.0%和97.2%～104.0%,结果良好.苯酚和苯胶的最低检出限分别为0.010和0.048μg·ml^-1.更多还原

【Abstract】 A method of simultaneous determination of phenol and aniline in refinery waste water by multi-wavelength linear regression UV-spectrophotometry is reported in this paper. The special features of the proposed method are its simplicity, accuracy and precision. Simulated samples were determined by the proposed method. The relative standard deviation obtained is less than 4. 57% , and the relative error is less than ?. 3%. The limit of detections for phenol and aniline are 0. 010礸 ?ml^-1 and 0. 048礸 ?ml^?-1? respectively.更多还原
