摘要
由于银杏叶下脚料呈膏状,不易溶于水,处理起来比较麻烦,多数厂家将其作为废物弃去,但银杏叶下脚料中含有大量的叶绿素,直接作为废物处理掉太过浪费,而且由于叶绿素铜钠盐具有实用价值,所以可以利用下脚料制成叶绿素铜钠盐。文章对在不同皂化、除杂和铜代条件下制得的叶绿素铜钠盐的总铜和游离铜含量进行了考察,研究了银杏叶下脚料制备叶绿素铜钠盐的工艺,最终得到了比以往的文献报道更有效的去杂质的方法和最佳的工艺路线。
Many manufacturers will discard the scraps left after the Ginkgo biloba extracted as waste. The Ginkgo biloba scraps contain large amounts of chlorophyll,and it is too wasteful when thrown away directly as the waste. Since sodium copper chlorophyllin has many practical values,it can be made through the use of Ginkgo biloba scraps. This paper investigated systematically the total copper and free copper contents of sodium copper chlorophyllin when prepared in the different conditions of saponification,purification and coppers replacement,and studied the process of the preparation of copper chlorophyllin sodium salt. Finally more effective methods to remove impurities than previous reported in literature and the best process route were obtained.
