提钪工艺中常使草酸钪溶于过量草酸铵溶液中。但文献中有关钪与草酸离子配位作用的报导甚少。等用分光光度法测定了ScC_2O_4~+配离子的稳定常数,而J·Stary则用分配法测定了SC(C_2O_4)_3~(3-)配离子的稳定常数,这些工作都没有对溶液中可能生成各级配离子进行研究。本文用溶度法研究了溶液中钪与草酸离子 Scandium scandium is often dissolved in an excess of ammonium oxalate solution in the scandium process. However, the literature on scandium and oxalate ion coordination role reported little. The spectrophotometric method was used to determine the stability constants of ScC_2O_4 + ions while J · Stary was used to determine the stability constants of SC (C_2O_4) _3 ~ (3-) ions by the partition method. Generation of ions at all levels to study. In this paper, the scandium and oxalate ions in solution were studied by the solubility method
