1903年Цвет在分离植物色素的工作中最先提出了色层分析法(chromatography,简称层析)。约三十年后Kuhn和Lederer以及后来的Brockmann,Karrer,Winterstein,Zechmeister等更进而在化学工作的提取、纯化和分析方面应用了并发展了这个方法。目前层析一项已成为化学实验的基本操作之一了。在层析剂方面由于活性氧化铝的性质比较稳定,吸附力强弱可以调节,便成了最常用的层析剂。最近我国各地的有些工厂,学校曾试制活性氧化铝以供生产及研究上应用。我们过去也曾进行了从山东张店501厂的水合氧化铝(或称氢氧化铝)制备各种活性氧化铝的试验,并检定了这些氧化铝的吸附及离子交换的性能,和几种进口货进行了比较,并在一些研究工作中使用,结果尚称满意。
1903 Цвет in the separation of plant pigments first proposed color chromatography (chromatography, referred to as chromatography). About thirty years later, Kuhn and Lederer, and later Brockmann, Karrer, Winterstein, Zechmeister and others, applied and developed this method for the extraction, purification and analysis of chemical work. One of the basic steps in chemical experiments has now been developed. In the aspect of chromatographic reagent, activated alumina can be the most commonly used chromatographic reagent due to the relatively stable properties of activated alumina. Recently some factories in our country, the school trial production of activated alumina for production and research applications. We have also conducted experiments in the past to prepare various kinds of activated alumina from hydrated alumina (or aluminum hydroxide) at Changdian No. 501 in Shandong Province and examined the performance of these aluminas for adsorption and ion exchange, as well as several types of imports Goods were compared, and used in some research work, the results are still satisfied.
