摘要
Abstract
Coupling C-T fixed-type grating with InGaAs detector,a new novel analytical instrument for measurement of nitric acid and Pu(Ⅳ)was successfully developed.Acquiring near infrared absorptive spectra (NIR spectra ) with the spectroscopic instrument and processing data with PLS technique,a rapid and non-destructive method for measuring the nitric acid and Pu(Ⅳ)of reprocessing fuel solutions was established.The instrument shows excellent performances such as rapid measurement,good reproducibility of wavelength,and higher stability.For the measurement of nitric acid and Pu (Ⅳ)in aqueous solutions,the simple,fast and non-destructive method yields wide determination ranges from 0.42-3.97 mol/L,1.07-25.26 g/L.关键词
