本文用紫外光度法测定了在不同体积配比的二甲基亚砜-水混合溶剂中,存在不同浓度硫氰酸根时,硫氰酸钴(Ⅱ)络合物的各级摩尔吸光系数和稳定常数及各级络离子的百分组成,表明了上述各项都随着体系中二甲基亚砜浓度的增加而不断增大。
In this paper, the molar extinction coefficient and stability at various levels of cobalt (II) thiocyanate complex in the presence of different concentrations of thiocyanate in dimethyl sulfoxide-water mixed solvents with different volume ratios were determined by UV spectrophotometry The constants and percentages of complexion ions at all levels indicate that the above items are all increasing as the concentration of dimethylsulfoxide in the system increases.
