| Abstract: | Trace benzene in cyclohexane was determined by derivative infrared spectroscopy. In the determination, we selected peak at 674 +/- 2 cm-1 as quantitative peak, and peak height, peak area, first derirative (maximum, minimum, region) and second derivative methods were used. The correlation coefficient of standard curve equations were in the range of 0.990-0.995. There is a linear relationship between absobance and concentration of solution in the range of 0.010-0.10 g.10 mL-1. A quick and precise method for the determination were provided. |
