常见光度分析用有机试剂(如双硫腙、偶氮染料、三苯甲烷染料、氧杂蒽酮、羟铵、菲绕啉、联吡啶、蒽醌、氨荒酸、肟、喹啉等类),使用者遍及世界各国。而安替比林染料则仅有很少报道,目前尚限于中苏两国作者应用。分光光度测定微量锡,常用二硫酚、茜素紫、邻苯二酚紫、苯基萤光酮及其衍生物等。本文则在SCN~-存在的酸性介质中,以阿拉伯树胶为分散剂,用双-(4-二甲胺苯基)-安替比林甲醇直接水相测定微量锡,显 Common photometric analysis of organic reagents (such as dithizone, azo dyes, triphenylmethane dyes, xanthone, hydroxylammonium, phenanthroline, bipyridine, anthraquinone, ammonia, acid, oxime, , Users all over the world. The antipyrine dye is only rarely reported, is still limited to the author of the two countries. Spectrophotometric determination of trace tin, commonly used dithiol, alizarin purple, catechol violet, phenyl fluorone and its derivatives. In this paper, SCN ~ - in the presence of acidic medium, with gum arabic as a dispersant, with bis - (4-dimethylaminophenyl) -antipyrine methanol direct water phase determination of tin, was
