A series of experiments were carried out to verify the basic principles of "inverse polarography" suggested by Hickling, Maxwell and Shennan. Results lead to conclusions quite different from those of the above workers. In the case of cadmium amalgam electrodes, within the amalgam, the diffusion of electro-active metal from interior to amalgam-solution interface obeys the general equation of linear diffusioni_t=nFACD~(1/2)1/(πt~(1/2)) Anodio half-wave potentials obtained from C-V curves have a definite...

1.本文驗証Hickling等的“逆向極譜”基本理論的主要論点,并証明鎘汞齐电極上的扩散屬于线性扩散类型,扩散电流强度与汞齐濃度遵守綫性扩散式, i_t=nFAD~(1/2)C(1/(πt~(1/2)),不同濃度的鎘汞齐所生的陽極波其半波电位为一定数值。 2.把汞齐体积改为4毫升,鎘汞齐濃度在2.37—9.46mM范圍內濃度与扩散电流成直綫关系,可作定量分析的基础。

The half wave potential of the thallous ion was determined at 25° insodium perchlorate-sodium thiocyanate mixtures over the range of 0.05--2.0M thiocyanate concentration at an ionic strength of 3.00. A modified typeof H-cell was proposed in order to prevent the diffusion of chloride ions fromthe calomel electrode to the solution being investigated. The errors in thedifference between the half wave potentials of the simple and the complexions were estimated to be less than ±0.2 mv. The treatment of the...

The half wave potential of the thallous ion was determined at 25° insodium perchlorate-sodium thiocyanate mixtures over the range of 0.05--2.0M thiocyanate concentration at an ionic strength of 3.00. A modified typeof H-cell was proposed in order to prevent the diffusion of chloride ions fromthe calomel electrode to the solution being investigated. The errors in thedifference between the half wave potentials of the simple and the complexions were estimated to be less than ±0.2 mv. The treatment of the datarevealed the existence of Tl+, TlSCN, Tl(SCN)_2~-, Tl(SCN)_3~=, Tl(SCN)_4~(3-), Tl(SCN)_5~(4-) and Tl(SCN)_6~(5-) in contrast to the results obtained by the previousinvestigators. The successive stability constants were found to be: K_1=4.38±0.04, K_2=7.59 ±0.18, K_3=5.04 ±0.19, K_4=5.37 ±0.42, L_5=3.33 ±0.52, andK_6=2.88 ±0.93.

The graft copolymerization of acrylonitrile onto cotton yarn and viscose rayon with eerie ammonium nitrate as initiator has been studied. It was shown that the grafting occured readily and the homopolymerization could be inhibited under proper experimental conditions. The grafting is believed to take place principally through the active centers which are formed on the cellulose substract by the action of eerie ion. It was also shown that the grafting was controlled by the diffusion of the solution to cellulose....

The graft copolymerization of acrylonitrile onto cotton yarn and viscose rayon with eerie ammonium nitrate as initiator has been studied. It was shown that the grafting occured readily and the homopolymerization could be inhibited under proper experimental conditions. The grafting is believed to take place principally through the active centers which are formed on the cellulose substract by the action of eerie ion. It was also shown that the grafting was controlled by the diffusion of the solution to cellulose. The grafting proceeded very rapidly at the begining and then leveled off to a limiting value, depending on the fine structure of the cellulosic material, as a result of the retardation of diffusion by the formation of polyacrylonitrile on the surface of the cellulose. A preliminary estimation was made on the properties of the grafted products.

以棉纱和粘胶丝为试料,研究了利用硝酸铵铈为引发剂的纤维素与丙烯腈的接枝共聚。研究各种影响反应的主要参数的结果说明所研究的接聚反应比较容易进行,同时可以选择适当条件使过程中的均聚反应受到抑制。可以认为,接聚反应的发生主要是通过铈离子与纤维素作用在纤维素上生成活性中心。所研究的接聚反应受着反应溶液向纤维素渗透的影响。反应开始进行甚快,但随着接聚或均聚的聚丙烯腈在纤维素表面上生成,使渗透受到阻碍,不同纤维素材料因其精细结构的不同,其接聚反应亦分别达到不同限度。此外,尚曾对所得产品的性能作了初步鉴定。
