This dissertation summarizes the research on the chemical analysis of cobalt oxalate and investigates the following methods respectively:potentiometric back titration for cobalt, graphite furnace atomic absorption spectrometry for lead, hydride generating-atomic fluorescence spectrometry for arsenic, molybdenum blue spectrophotometry for silicon, flame atomic spectrometry for calcium, magnesium and sodium, ion selective electrode method for chloride anion. The measurement condition is optimized, and the disturbance caused by matrix cobalt and other element existing in the measured solution is investigated and eliminated with appropriate technique. The precision and accuracy is evaluated by determining actual samples. The methods established in this dissertation may meet enterprises, customers and assaying organization to measure cobalt oxalate in its suitable range with enough precision and accuracy. This task fills the gap of the methods for chemical analysis of cobalt oxalate at home and abroad. |
