漂蓝6B属三苯甲烷酸性染料,是铬天青S的同类物。文献对该试剂的制备和纯化,纯度测定和光度特性,以及在光度分析中的应用作了详细介绍,并介绍了在表面活性物质存在下,试剂和某些金属离子的显色反应,并探讨了反应机理。文献研究了在十六烷基三甲基溴化铵存在下,铀和漂蓝6B的反应,获得了较高的灵敏度(ε_(630)=9.6×10~4)。 本文研究了在苄基十四烷基二甲基氯化铵存在下,铀和漂蓝6B的反应,灵敏度有所提高 Bleaching blue 6B is a triphenylmethane acid dye, is similar to the blue sky chrome S material. Literature on the preparation and purification of the reagent, purity determination and photometric properties, as well as in the application of photometric analysis are described in detail, and introduced in the presence of surface-active agents, reagents and some metal ions color reaction, and to explore The reaction mechanism. The literature studies the reaction of uranium and bleached blue 6B in the presence of hexadecyltrimethylammonium bromide to obtain a high sensitivity (ε_ (630) = 9.6 × 10 ~ 4). In this paper, the reaction of uranium and bleached blue 6B in the presence of benzyltetradecyldimethylammonium chloride has been studied and the sensitivity has been increased
