| 摘 要： | 采用邻菲罗啉比色法和硫氰酸根比色法对加氢裂化原料油中的铁含量进行了测定,并将其与电感耦合等离子体发射光谱法(ICP-AES)的测定结果进行了比较。对于邻菲罗啉比色法,Fe2 在0.06~2.00 m g/L遵守朗伯-比尔定律,线性回归方程为A=0.397 3c-0.001 5,R2=0.999 7;对于硫氰酸根比色法,Fe3 在0~8.00 m g/L遵守朗伯-比尔定律,线性回归方程为A=0.142 1c 0.007 6,R2=0.999 9。结果表明:两种测试方法操作简单,准确度高,精密度好,测定结果与ICP-AES的结果一致。

| Abstract: | Two sensitive spectrophotometric methods were developed for the determination of iron in hydrocracking raw oil.At the range of 0.06-2.00 mg/L for Fe~(2 ) concentration,Beer's law is followed and the regression equation is A=0.397 3c-0.001 5,R~2=0.999 7 for 1,10-phenonthroline spectrophotometry.For thiocyanato spectrophotometry,Beer's law is obeyed at the range of 0-8.00 mg/L for Fe~(3 ) concentration,the regression equation is A=0.142 1c 0.007 6,R~2=0.999 9.The results show that two methods are precise and sensitive,and the determination results are consistent with that of inductively coupled plasma atomic emission spectrometry(ICP-AES). |
