摘　　要：应用凝胶过滤色谱、2 7Al核磁共振及 X射线衍射等测试技术 ,研究了有机酸蒙囿硫酸铝配合物溶液的组份及组份的结构。结果表明 :在 p H值约 3.5时 ,绝大部分组成成份为“Al13 族”多核配合物。洗脱流份的2 7Al核磁共振图表明 ,所采用的凝胶过滤色谱分离体系的总趋势符合基本原理 ,但大分子的多核铝配合物离子对小分子的配合物离子有吸附现象 。The composition and structure of organic acid masked aluminum (Ⅲ)complexes were analyzed by means of GFC、 27 AlNMR and X-ray diffration etc. The results indicated that most of compositions were“Al 13 Like” multimeric complexes. The NMR spectras of elution fractions showed that the general tendency was tallied with the GFC elution system, but there were a little amount of oligomeric species were adsorbed by multimeric complexes, complete seperating was impossible by the applied GFC system.
