我国有色金属化学分析自动化研究工作取得了一些进展,现择数则实例报道如下。 1975年开始,新疆冶金研究所王克俊、刘佩君、陈新等人对自动光度滴定仪的制作及应用方面的问题进行了探索,并制作了一台自动光度滴定仪。该仪器滴定过程自动进行,滴定速度可以自动调整。据报道,对钙、镁、锆、铪等元素的EDTA滴定及铁的重 China’s nonferrous metal chemical analysis automation made some progress, the number of examples are now reported as follows. Since 1975, Xinjiang Institute of Metallurgy Wang Kejun, Liu Peijun, Chen Xin and others on the automated photometric titration of the production and application of the problem were explored and produced an automatic photometric titrator. The instrument titration process automatically, titration speed can be automatically adjusted. It has been reported that EDTA titration and iron weight for elements such as calcium, magnesium, zirconium and hafnium
