摘要: 建立了一个快速检测酱油中硼酸含量的分光光度法,酱油中的硼酸直接用乙基己二醇-氯仿溶液萃取后,在浓硫酸酸性条件下,与姜黄反应生成玫瑰蓝染料。在5~500μg/ml范围内吸光度与硼酸浓度呈线性关系,相关系数为0.9997。重现性良好。
关键词: 萃取, 分光光度法, 硼酸, 酱油, 姜黄
Abstract: A spectrophotometry method is established to rapidly determine boric acid in sauce. boric acid in sauce is extracted with 2-ethyl-1,3-hexanediol-chloroform. Boric react with curcuma forming rose-bule dye.Beel’ law is obeyed in the range of 5~ 500μg/ml with r =0.9997.The repeatability is satisfying.
Key words: extract, spectrophotometry, boric acid, sauce, curcuma
