| 摘 要： | 报道应用紫外分光光度法测定河水中五氨酸含量。水样经蒸馏处理后在２４８ｎｍ波长下直接测定。本法相对误差．２５％，添加回收率９６％～９９％．结果说明，与现行的比色法和气相色谱法比较，本方法简便、快速，最低检出浓度０．１０ｍｑ／Ｌ，能满足实际工作诗要，便于推广应用。

| Abstract: | his paper discribes a ultraviolet spectrophotometry for measuring pentachlorpheneol in riverwater. With this method,samples treated by clistillation was diectly measured at 248nm. Relativeerror was 1. 25%. Addition Percent recovery was from 96% and 99%. Compared with colorimetryand gas chromatogtaphy which are advanced methods, this method is proved to be easy, simple andprompt. The minimum detecable concentration is 0. 10mg/L,suitable for practical use. It is easy touse the may be popularized. |
