摘要
用分光光度法同时测定脱硫溶液中栲胶和“888”含量,结果表明,吸收波长分别为450nm和650nm,栲胶、“888”在使用浓度范围内,符合线性关系。该方法操作简易,结果准确。
The contents of tannin extract and desulfur catalyst " 888" were measured simultaneously with spectrophotometer. The measured results showed that there existed a linear correlation between absorbance at 450 nm and 650 nm and concentration of tannin extract and desulfur catalyst "888", respectively. The method had characteristic of simple operation and accuracy.
