This paper reports the polarographic behavior of the complex of Y3 + with basic dye rhodamine B.Near -1.5V (SCE) rhodamine B has a large adsorptive single sweep polarographic wave in the presence of ammonium chloride and diphenylg-uanidine. Y3+ decreases the height of this derivative wave. Under the optimum conditions, such as 0.4.M ammonium chloride, 8.0×10-5M rhodamine B, 1.0×10-4M diphenylguanidine, pH 4.5-5.0, there is a linear relationship between 1 × 10-7 - l×10-6M Y3+ and the decrease of the wave heights....

This paper reports the polarographic behavior of the complex of Y3 + with basic dye rhodamine B.Near -1.5V (SCE) rhodamine B has a large adsorptive single sweep polarographic wave in the presence of ammonium chloride and diphenylg-uanidine. Y3+ decreases the height of this derivative wave. Under the optimum conditions, such as 0.4.M ammonium chloride, 8.0×10-5M rhodamine B, 1.0×10-4M diphenylguanidine, pH 4.5-5.0, there is a linear relationship between 1 × 10-7 - l×10-6M Y3+ and the decrease of the wave heights. Heavy rare earth elements behave similarly as Y3 + , thus the total amount of them may be determined.The mechanism of this system has been studied by means of dc, dpp, single sweep normal and derivative polarographys. The results indicated that Y3+ may form an ion-association complex with rhodamine B and diphenylguanidine as shown in the following.The complex adsorbs strongly and occupies the partial surface area of the mercury drop. The complex reduces at more negative potential than rhodamine B, thus the wave height of rhodamine B itself decreases correspondingly. The two steps can't be separated In dc and single sweep normal polarograms and they interfere each other in dpp owing to the slow scan rate of pulse polarograph, there is no good linear: relatjonskip between the concentration and wave height. A sensitive wave only exists in the single sweep derivative polarography.

本文探讨了Y~(3+)与碱性染料罗丹明B络合物的极谱行为。 在NH_4Cl底液中,二苯胍存在下,罗丹明B在-1.50伏(SCE)附近有一个大而稳定的极谱吸附还原波,Y~(3+)使示波导数波降低。在最佳实验条件下,在1×10~(-7)-1×10~(-6)M的范围内Y~(3+)浓度与波高降低有良好线性关系。重稀土行为相似,可能用于测定重稀土总量。 通过i-t曲线,循环伏安图、比较dc、dpp、示波极谱常规波和导数波,研究了体系的还原机理。Y~(3+)与罗丹明B和二苯胍可能形成离子缔合络合物,强烈吸附并占据滴汞表面。络合物在罗丹明B还原波后还原,致使罗丹明B本身的波降低。在dc和示波常规波中。两波不能分开,在dpp中因电压扫描慢,无良好线性关系。只有在示波导数波上表现为一种灵敏的极谱波。

The least square method was used in the experimental data refinement. The lattice constants of these rare earth complexes were calculated. It was found that the volume of the unit cell of the complexes is decreasing and the crystal density of the complexes is increasing with increasing atomic numbers of...

随着我国国民经济建设的不断发展,尤其是渤海油气资源的大力开发,对渤海冰情资料的需求越来越多,越来越细,应用现有手段获得的海冰资料已远远满足不了用户的要求。为了使我国海冰监测技术提高一步,以便将来能实时准确地提供渤海海上冰情资料,适应各行各业的需要,更好地为四化建设服务,1985年2月1日至17日,国家海洋局海洋环境预报中心和海洋技术研究所共同组织了我国首次渤海海冰航空遥感试验。根据我国的冰情,这次试验选用了我国自己研制的多光谱摄影机、彩红外摄影机、慢扫描透射式红外测温仪、机载八毫米成象微波辐射计等配套设备。在全体参加人员的共同努力下,整个试验取得圆满成功,获得了大量的海冰遥感资料和图象。试验结果表明,航空遥感技术在海冰监测中将大有作为,并能发挥越来越大的作用,为广大用户及时提供更丰富、更准确的海上冰情资料。
