ABSTRACT

The application of short-wave NIRS (SW-NIRS) in determining acidity of aviation kerosene was described in term of chemometrics, and compared with long-wave NIRS (LW-NIRS). The standard error of prediction (SEP) of SWNIRS and LW-NIRS were 0.097 mgKOH/100mL and 0.091mgKOH/100mL respectively. A t-test showed that the SWNIRS model and LW-NIRS one all had an accuracy equivalent to that of GB/T7304 in the analysis of acidity of aviation kerosene. However the SW-NIRS method had the particular advantage of cheaper analysis cost than LW-NIRS. In results, SW-NIRS possessed the important application significance in the course of general test and production monitor.
