由于催化动力学分析法具有很高的灵敏度,且所用仪器较为简单,故为分析化学工作者所重视并得到不断发展。其测试方法一般都需要测量反应时间与指示反应的参数(吸光度、电位…等)变化的关系,进而计算被测组份的含量。连续自动记录这个关系,无疑会给动力学分析法提供方便和准确的测试手段。国外已有这方面的工作,但国内尚未见报导。我们利用721型分光光度计、pHS-2型酸度计(配合离子选择性电极)、501型超级恒温水浴、XWC-100自动记录仪、电磁搅拌器等这些常见仪器进行组合,实现催化动力学分析法的连续自动记录,通过对几个具
Due to the high sensitivity of the catalytic kinetic analysis and the simplicity of the instrumentation used, analytical chemists value and are constantly evolving. The test method generally need to measure the reaction time and the reaction parameters (absorbance, potential ... etc) changes in the relationship, and then calculate the content of the measured components. Continuous automatic recording of this relationship will undoubtedly provide a convenient and accurate method of kinetic analysis. Foreign countries already have work in this area, but no reports have yet been made in China. We use 721 spectrophotometer, pHS-2 pH meter (with ion selective electrode), 501 super-heated water bath, XWC-100 automatic recorder, electromagnetic stirrer and other common instruments for combination to achieve catalytic kinetic analysis Law of continuous automatic recording, through a few with
