摘要
采用 75 2紫外分光光度法对从工业废水提取的矿物油品的吸收波长进行了实验 ,找出了最佳吸收波长 2 2 5 nm ,并于此波长处做出了标准曲线 ,用该方法测定矿物油密码样 ,其准确度和精密度都非常好 ,该方法具有操作简单、灵敏度高等优点。
The absorbable wavelength of mineral oil in industrial waste water was investigated by using 752 ultraviolet spectrophotometry.The most favorable absorbable wavelength was at 225nm.Standard curve was set up at 225nm.This method exhibited sensitively and simply and accurately.
