摘要

褐藻胶在食品、医药、纺织、科学研究以其产品规格的鉴定方面都迫切地需要一个简单而准确的定量方法，以便测定褐藻胶样品或者褐藻样品中的褐藻酸实际含量。自然，这对于研究褐藻的生理生化现象也是很重要的。褐藻酸的定量方法至目前为止在文献中可查到的大致可分为重量法、滴定法、CO,2,法、比色法。这些方法各有利弊，至今还没有一个很理想的定量方法。 9-氮杂芴法简便，所用试剂便宜。此方法中存在一些缺点，本工作的目的在于改进此操作方法、使其简化，适于大量分析。

Abstract

Among the methods for the determination of alginic acid in brown algal samples,the carbazole colorimetric method is the most convenient and accurate one.But the method as employed by earlier workers has many drawbacks and so up to date it was seldom used. 1n the present investigation we have tried to improve the method and make it practicable for alginic acid determination in the routine analysis of algal samples.
