提高极谱法的灵敏度、分辨率和精确度,扩大其应用范围并消除汞害,使极谱法连续自动化以进行流程分析,以及完善和发展极谱理论,是国际上极谱法发展的主要趋势。为了解决上述问题,近年来在仪器制造技术上有了飞速的发展。示波、方波、射频和脉冲等新型极谱仪的出现,大大提高了极谱分析的灵敏度和分辨率;各种新颖固体电极和阳极溶出法的研究,使得极谱分析的灵敏度达到10~(-9)M,若能
Increasing the sensitivity, resolution and accuracy of polarographic methods, expanding their range of application and eliminating mercury hazards, and continuously automating polarographic methods for process analysis, as well as the development and improvement of polarographic theory are among the major developments in polarography worldwide trend. In order to solve the above problems, in recent years the rapid development of the instrument manufacturing technology. The emergence of new polarographic instruments such as oscillography, square wave, radiofrequency and pulse greatly improves the sensitivity and resolution of polarographic analysis. The research of various novel solid electrodes and anodic dissolution method makes the sensitivity of polarographic analysis reach 10 ~ (-9) M, if possible
