摘要
以前,室温下在较低pH值范围内络合滴定Cu^(2+)、Co^(2+)、Ni^(2+)等离子是不可能的,现在利用二甲酚橙金属螯合物水溶液的热色性,使这成为可能。
The complexometric titrations of Cu^(2+), Co^(2+), Ni^(2+)ions in a low(?)H region at room temperature were impossible before, now they were carried out bas(?)d on the thermochromism for the metal complexes of xylenol orange.
