THE TRANSFER BEHAVIOUR OF SOME CATIONS AT WATER／NITROBENZENE INTERFACE BY SEMIDIFFERENTIAL CYCLIC VOLTAMMETRY

The transfer of Sr~(2+) and Ba~(2+) ion, facilitated by 18-Crown-6 present in the aqueous phase, and of succinylcholine ion at w/nb interface were investigated by semi-differential cyclic voltammetry. A good polarographic curve of succinylcholine ion dissolved in water was obtained in the system of 0.01 mol/l LiCl (w)——0.01 mol/l TBATPB (nb). The peak current is directly proportional to the concentration of SC~(2+) ion. It can be used for the determination of SC and the detection limit is 1.05×10~(-5) mol/l.The apparent D~w and D~(nb) have been estimated. The transfer of Sr~(2+) and of Ba~(2+) at the interface are facilitated by 18-Crown-6 present in the aqueous phase and the peak current is directly proportional to the concentration of 18-Crown-6 in water. This method can be used for the determination of the complexing agent and for the stability constant of the complex formed in the aqueous phase.All the experimental results are in keeping with the theoretical.     

聚合物/纤维级氢氧化镁超细粉复合材料

高分子材料的阻燃研究经历了含卤阻燃、低卤阻燃到无卤阻燃的发展过程，特别是无机阻燃剂Al（OH）3、Mg（OH）2的研究与应用日益广泛。Mg（OH）2的分解温度为340℃,比Al（OH）3高100℃左右，更适用于高加工温度下的高分子材料阻燃。与普通Mg（OH）2相比,纤维级Mg（OH）2具有较大的长径比，更有利于提高材料的拉伸性能和；中击性能，一定程度上能起到玻璃短纤维的作用。为了理论推测，我们开展了此项课题研究。并得到如下结果：
