초록
원자력 산업의 변환공정에서 발생하는 폐수용액중의 우라늄 농도를 레이저 유발형광법을 사용하여 쉽게 측정할 수 있는 새로운 분석방법을 개발하였다. 실험 결과 시료의 약 10배 이상의 부피로 4M-인산용액을 첨가함으로써 효율적으로 형광 quencher의 영향을 배제시킬 수 있었으며, 폐액 시료에서의 우라늄 농도 3.0
A simple and new uranium analysis technique for raffinate solution of nuclear fuel conversion process was developed using a time-resolved laser-induced fluorimetry. The addition of 4 M-phosphoric acid more than 10 times in volume to the raffinate sample was found to be efficient for obtaining stable uranium fluorescence signal which was not influenced by many fluorescence quenchers. A calibration curve of a good linearity for the fluorescence intensity vs. the uranium concentration was obtained at the range of 3.0
