摘要
还原－偶氮光度法测定硝基苯，改用ＮａＯＨ调节至出现白色絮状沉淀，再加入２００ｇ／ＬＫＨＳＯ４溶液１ｍＬ调节ｐＨ，可省去原方法中两步测试ｐＨ过程，更易操作。
The modified steps of Nitrobenzene determination with reduction-azo Colorimetry are as follows: putting NaOH till white tassel-like cluster in sample solution then adding into 1mL KHSO4 and adjusting PH. The modified steps are easily perform and better for analytical accuracy.
