摘要

在与磺基水杨酸衍生物的配合物中寻找与铽的发光反应,并通过研究第三组分(氨基聚羧酸、有机碱和表面活性剂)的影响来加强这些反应是很有兴趣的。用SF-26分光光度计记录了稀土配合物溶液在220 ~ 880 nm波长范围内的吸收光谱。为了获得稀土元素与有机试剂配合物的发光反应的最大发光,研究了一些对发光配合物溶液强度有显著影响的因素。这些因素包括配合物的pH值、试剂的浓度、配合物的成熟时间、辐照时间、试剂的加入顺序和溶液的离子强度。根据所进行的研究,表面活性剂增加了与磺基水杨酸衍生物配合物中铽离子的光度。在溶液中使用十二烷基吡啶作为表面活性剂。证实了铽与S-(4-溴酰亚胺)磺基水杨酸甲酯配合物存在亮绿色发光反应。选择了铽络合的最佳条件,开发了高灵敏度的荧光法测定各种物体中的铽。在阳离子表面活性剂十二烷基吡啶的存在下,铽与有机试剂S-(4-溴苯胺)磺基水杨酸甲酯以1:2:13的比例(pH 7.9±0.08)转化为发光配合物。在紫外光照射下,用汞灯照射产生的铽复合化合物发出强烈的绿光,在站立和照射期间都是稳定的。因此,该方法可以跳过萃取阶段,以10-8%的灵敏度测定稀土元素氧化物中的铽,稀土元素是发光猝灭剂。剩余镧系元素氧化物中铽的测定灵敏度为2.4·10-10%。

LUMINESCENT PROPERTIES OF TERBIUM WITH S- (4-BROMANILIDE) METHYL ETHER OF SULFOSALICYLIC ACID
It was of interest to search for luminescent reactions to terbium in complexes with sulfosalicylic acid derivatives and to strengthen them by studying the influence of the third components (aminopolycarboxylic acids, organic bases, and surfactants). Absorption spectra of solutions of rare earth element complexes in the wavelength range of 220-880 nm were recorded using the SF-26 spectrophotometer. To obtain the maximum luminescence of the luminescent reaction of rare earth elements in complexes with organic reagents, a number of factors that have a significant impact on the intensity of solutions of luminescent complexes have been studied. Such factors are the pH of the complexes, concentration of reagent, time of maturation complexes, the irradiation time, the order of adding the reagents and the ionic strength of the solutions. According to studies conducted, surfactants increase the luminosity of terbium ions in complexes with sulfosalicylic acid derivatives. As a surfactant, decylpyridinium chloride was used in solutions. The existence of a bright luminescent green reaction of terbium in a complex with methyl ester S- (4-bromanilide) sulfosalicylic acid was established. The optimal conditions for the complexation of terbium were selected and highly sensitive luminescent methods for determining terbium in various objects were developed. Terbium is converted into a luminescent complex compound with an organic reagent S- (4-bromanililide) sulfosalicylic acid methyl ester in the presence of a cationic surfactant decylpyridinium chloride in a ratio of 1: 2: 13, pH 7.9 ± 0.08. The resulting complex compound of terbium upon irradiation with a mercury lamp under ultraviolet light gives intense green luminescence that is stable during standing and irradiation. As a consequence, the proposed method allows to determine terbium in the oxides of rare earth elements, which are quenchers of luminescence with a sensitivity of 10-8%, bypassing the extraction stage. The sensitivity of the determination of terbium in the oxides of the remaining lanthanides is 2.4·10-10%.
