催化动力学分光光度分析是一种灵敏度高、设备简单、操作方便、易于推广的定量方法,在环境监测、岩矿测试、冶金分析、卫化实验等领域受到重视。至今,对于这类方法的灵敏度和检出限,国内外文献报导的数据存在混乱,难以进行对比研究,对于灵 Catalytic kinetic spectrophotometry is a quantitative method with high sensitivity, simple equipment, convenient operation and easy popularization. It is valued in the fields of environmental monitoring, rock and mine testing, metallurgy analysis and defensive experiments. To date, the sensitivity and detection limits of such methods have led to confusion in the data reported in the literature both at home and abroad, making it difficult to conduct comparative studies.
