分光光度法研究镧(Ⅲ)与芦丁(Rutin)的配合物(Ⅰ)

Studies on the Complex of La (Ⅲ) with Rutin by Spectrophotometry

本文报导了用分光光度法研究镧(Ⅲ)与芦丁形成配合物的条件和配合物的组成,以及测定出的配合物稳定常数。

The formation conditions and constitution of the complex of La(Ⅲ) with Rutin were studied by spectrophotometry. Stability constant of the complex was tested. Results are as follows: La (Ⅲ) -Rutin as 1:2, K=2.43×10~9. (t=25℃,ionic strength I=0.02 and water: alcohol=1:1).
