Development of a laser induced photoacoustic spectroscopy system for analytical technique of Np ion in the PUREX process

Technical Report:

Abstract

A new system of laser induced photoacoustic spectroscopy (LIPAS) has been developed for Np ions in PUREX process. The LIPAS system is composed of a YAG laser driven dye laser, a flow type cell with piezoelectric transducer (PZT) and digital storage oscilloscope. In the case of neodymium analysis, which was used as a simulant for Np ion, the detection limit absorptivity was 3.1 x 10{sup -5} cm{sup -1} and the detection limit concentration was 4.4 x 10{sup -6} M. These values show that the sensitivity of the present LIPAS system is two orders higher than that of spectrophotometry. The system has been applied to analyze Np(V) in nitric acid. In order to protect PZT from corrosion, the surface of PZT was coated with poly-vinyl chloride. The detection limit absorptivity was 3.6 x 10{sup -5} cm{sup -1} and the detection limit concentration was 1.8 x 10{sup -6} M for the system. These values are two orders lower than that of spectrophotometry. The photoacoustic (PA) signal of Np(V) ions is amplified by coexisting uranium ions, Magnitude of the amplification was reported to be inversely proportional to the specific heat of solution. It was found that the signal intensity of Np(V) in the  More>>

It was found that the signal intensity of Np(V) in the Np-U solution agrees well with the multification product of specific heat of uranium and the PA signal of Np(V) for Np solution without uranium. The detection limit concentration of Np(V) for Np-U solution was 2.5 x 10{sup -6} M. This value indicates that the LIPAS system is able to determine Np(V) ions in PUREX process. The feasibility of the LIPAS system is studied for analytical technique of PUREX process. (author).}
