用反相气相色谱法研究了聚硫醚为主链,乙二胺交联的螯合树脂在络合金前后的热力学性质的变化,对其络合情况提供了有价值的信息。 实验结果表明,比保留体积与载气流量、探针分子的注入量有关,需外推求出无限稀释时的比保留值,从而可以求出聚合物—溶质的相互作用参数、偏克分子混合自由能、熔质分子的溶解热等热力学函数值,同时求得高聚物的溶度参数。 The reversed-phase gas chromatography was used to study the change of the thermodynamic properties of the polythioether-based chelating resin with ethylenediamine cross-linked chelating resin before and after gold complexation, which provided valuable information for its complexation. The experimental results show that the ratio of retention volume to carrier gas flow rate and the amount of probe molecule injected are extrapolated to obtain the specific retention at infinite dilution, so that the polymer-solute interaction parameters, Free energy, the melting heat of molten molecules and other thermodynamic function values, and also get the solubility parameters of the polymer.
