本文介绍了在酸性介质中,稀土钇(Ⅲ)分别与邻苯二酰异羟肟酸(O-PhHA)、乙二酰异羟肟酸(OXHA)及己二酰异羟肟酸(AdHA)反应生成配合物的方法。对配合物进行红外光谱和热重分析法研究,并用PH滴定法求出它们的稳定常数K稳依次为1.90×10~(21)、4.17×10~(21)及5.15×10~(31)。
In this paper, the effects of rare earth yttrium (Ⅲ) with o-PhHA, OXHA and AdHA in acidic medium were described. The reaction produces a complex. The complex was studied by infrared spectroscopy and thermogravimetric analysis. The stability of the complexes was found to be 1.90 × 10 ~ (21), 4.17 × 10 ~ (21) and 5.15 × 10 ~ (31) .
