摘要
用胭脂红酸分光光度法测定废水中的硼 ,着重进行了方法的条件和干扰试验。方法检测限为 0 0 63mg/L ,线性范围为 0 2 1mg/L～ 1 2 5mg/L。 5个实验室对 5 0 0mg/L硼标准样品测得重复性相对标准差为 3 4% ,再次性相对标准差为 3 6% ;相对误差为 - 0 8%～ 1 4% ,回收率在 95 2 %～ 1 0 4 6%之间。
In the experiment to determine boron in wastewater with carminic acid spectrophotometry, the condition to use this method and the disturbance factors were especially researched. The detection limit was 0 063 mg/L, linear limit was 0 21 mg/L ～1 25 mg/L. For the standard samples of 5 00 mg/L boron in five laboratories, the repetitively relative standard deviation was 3 4%, reappearance relative standard deviation was 3 6%. And the relative error was -0 8%～1 4%, the recovery rate was 95 2%～104 6%.
