摘要
亚硝酸根广泛地存在于土壤、水体、食品等物质中,是水质、环境、食品等检测的重要项目.建立简便、快速、灵敏的测定亚硝酸根的方法,在食品和环境分析中具有重要意义.本文综述了催化动力学法测定NO2的发展状况,包括反应体系、线性范围、检出限、应用对象等,还探讨和展望了催化动力学法测定NO2的研究方向和发展前景.
Nitrite which exists widely in the soil, natural water and food , etc, is one of the most important indexes to test the water quality , environment quality and foodstuff quality . It has practical significance to look for the simple , rapid , sensitive methods of determining nitrite. The development of catalytic kinetic determination of nitrite is reviewed in this paper . The indicator reaction , detection limit , linear range and applications of the methods are involved. Finally , the development tends and application perspectives for the catalytic kinetic determination of nitrite in the future are discussed.
