A basic study of distribution behavior of some ion-pairs between an aqueous and a solid comprising phenyl group in its structure was performed. Strong affinity between the ion-pairs and the phenyl group on the solid was observed. The π-cation interaction may be strong enough to cause such an interesting phenomenon. A phenyl-modified silica gel column was applied to the preconcentration and spectrophotometric determination of cationic surfactant in environmental waters.New solid-phase extraction methods using several membrane filters were proposed for the determination of environmental trace species in water. (1) Solvent-insoluble and -soluble membrane filters were used to the successive process of separation and spectrophotometric determination of cationic surfactant in water. (2) A solvent-soluble membrane filter was applied to the atomic absorption spectrophotometric determination of arsenic and copper-reactive pesticides.(3) A transparent membrane filter was also used to the spectrophotometric determination of cationic surfactant. (4) Membrane-enrichment and X-ray fluorescence measurement system was applied to the determination of sulfur comprising anionic surfactant in environmental water.

本文研究了一些离子对在水溶液和含有苯基的固体之间的分配行为。观察到离子对与固体上的苯基之间的强亲和力。π-阳离子相互作用可能足够强以引起这种有趣的现象。采用苯基改性硅胶柱对环境沃茨中的阳离子表面活性剂进行预富集和分光光度测定，提出了一种多滤膜固相萃取测定环境水样中痕量阳离子表面活性剂的新方法。(1)采用溶剂不溶性和溶剂可溶性膜过滤器对水中阳离子表面活性剂进行连续分离和分光光度测定。(2)采用溶于溶剂的滤膜，原子吸收分光光度法测定砷、铜反应性农药。(3)用透明膜过滤器分光光度法测定阳离子表面活性剂。(4)采用膜富集-X射线荧光光谱法测定环境水样中的含硫阴离子表面活性剂。
