烷基多胺与过渡金属离子Cu（Ⅱ）的络合研究

Study on Complexing of Alkyl Polyamine with Transition Metallic Ion Cu(Ⅱ)

研究了几种长链烷基多胺与Ｃｕ（Ⅱ）的络合物的最大吸收波长、络合比及络合物的稳定常数。结果表明，该类化合物可与Ｃｕ（Ⅱ）有效地络合，但络合物的稳定性和水溶性均比相应未取代的络合物的稳定性和水溶性差。为９０％乙醇中测得。

The absorption maximum wavelength,complexing ratio and stability constants of complexes of several long-chain alkyl polyamines with Cu(Ⅱ) were studied.The results show that the above-mentioned polyamines can complex effectively with Cut(Ⅱ),but their complexes are inferior to the unsubstituted polyamines in stability and water-solubility.
