摘要：
The preparation of adsorbents for capillary CGC has been described. The adsorbents have a free ketoimine group which enables to bound copper(II) and nickel(II) chlorides. The prepared adsorbents have been characterised by such physico-chemical techniques as elemental analysis, differential scanning calorimetry (DSC) and electron spin resonance (ESR), in addition to the characterisation performed by using chromatographic methods. The nature of adsorbate-adsorbent interactions was interpreted for the group of compounds studied. An attempt has been also made at solving the structure of surface complex formed.
