近几十年开展起来的区域化探扫面工作,对B的分析方法既要灵敏度高,又求简便快速。光度法测定B的有机试剂及分析方法虽然不少,如姜黄素、羟基蒽醌、次甲基蓝、甲亚胺-H酸等,但或因方法灵敏度低,或因操作繁琐,使它们在化控扫面的应用上受到了限制。 文献提出B与8—羟基萘—3,6—二磺酸—(1-偶氮-1)—2,4—间苯二酚及劳氏青莲在微酸性溶液中,能够生成红紫色的离子缔合物,表
In recent decades, the regional geochemical exploration work carried out on the B of the analytical methods to both high sensitivity, but also seek quick and easy. Although there are many organic reagents and analytical methods for the determination of B by spectrophotometry, such as curcumin, hydroxyanthraquinone, methine blue and azomethine-H acid, the sensitivity of the method is low or the operation is cumbersome, The application of chemical control scanning has been limited. The literature proposes that B and 8-hydroxynaphthalene-3,6-disulfonic acid- (1-azo-1) -2,4-resorcinol and lloyd’s Chrysanthemum in slightly acidic solution, capable of generating magenta Ion complex, table
