The Measurement of the Main Component in Cobalt Oxide
摘要
Abstract
To measure the main component in cobalt oxide,a EDTA volumetry is recommended. In this method, the
testing sample was dissolved in hydrochloric acid solution, then the malachite green was added as back lining re
agent and the xylenol orange was taken as indicator. Compared with other methods,the method mentioned above has ad
vantages of the easy judgment of equivalent point, acute color transformation, rapidity and high accuracy.关键词
