HPD100A大孔吸附树脂 HPD100A大孔吸附树脂 产品名称:HPD100A大孔吸附树脂 产品编号:A2111英文别称 HPD100A Macroporous Adsorption Resin 包装 瓶 规格 500g大孔吸附树脂是一类不含交换基团且有大孔结构的高分子吸附树脂,具有良好的大孔网状结构和较大的比表面积,可以有选择地通过物理吸附水溶液中的有机物,是20世纪60年代发展起来的新型有机高聚物吸附剂,已在环保、食品、医药等领域得到了广泛的应用。
吸附机理: 产品用途: 大孔吸附树脂吸附技术最早用于废水处理、医药工业、化学工业、分析化学、临床检定和治疗等领域,近年来在我国已广泛用于中草药有效成分的提取、分离、纯化工作中。与中药制剂传统工艺比较,应用大孔吸附树脂技术所得提取物体积小、不吸潮、易制成外型美观的各种剂型,特别适用于颗粒剂、胶囊剂和片剂,改变了传统中药制剂的粗、黑、大现象,有利于中药制剂剂型的升级换代,促进了中药现代化研究的发展,国家中医药管理局等单位联合发布的2002~2010《医药科学技术政策》明确提出:研制开发中药动态逆流提取、超临界萃取、中药饮片浸润、大孔树脂分离等技术。 使用方法: 在运用大孔吸附树脂进行分离精制工艺时,其大致操作步骤为:大孔吸附树脂预处理——树脂上柱——药液上柱——大孔吸附树脂的解吸——大孔吸附树脂的清洗、再生。由于每一个操作单元都会影响到大孔吸附树脂的分离效果,因此对大孔吸附树脂的精制工艺和分离技术的要求就相对较高 HPD100A Macroporous Adsorption Resin HPD100A Macroporous Adsorption Resin Product Name: HPD100A Macroporous Adsorption Resin Product Number: A2111 English alias HPD100A Macroporous Adsorption Resin Packaging Bottle Specification 500g Macroporous adsorption resin is a type of polymer adsorption resin that does not contain exchange groups and has a macroporous structure. It has a good macroporous network structure and a large specific surface area, and can selectively adsorb organic matter in aqueous solutions through physical adsorption, It is a new type of organic polymer adsorbent developed in the 1960s and has been widely used in fields such as environmental protection, food, medicine, etc.
Adsorption mechanism:
Product Usage:
The macroporous adsorption resin adsorption technology was first used in fields such as wastewater treatment, pharmaceutical industry, chemical industry, analytical chemistry, clinical testing, and treatment. In recent years, it has been widely used in the extraction, separation, and purification of effective ingredients in Chinese herbal medicine in China. Compared with traditional Chinese medicine preparations, the application of macroporous adsorption resin technology results in various dosage forms of small volume, non hygroscopic, and easy to produce aesthetically pleasing extracts. It is particularly suitable for granules, capsules, and tablets, changing the coarse, black, and large phenomena of traditional Chinese medicine preparations, which is conducive to the upgrading and upgrading of Chinese medicine preparation dosage forms, and promoting the development of modern research on Chinese medicine, The "Medical Science and Technology Policy" jointly issued by the National Administration of Traditional Chinese Medicine and other units from 2002 to 2010 clearly proposes the development of technologies such as dynamic countercurrent extraction, supercritical extraction, infiltration of traditional Chinese medicine slices, and separation of macroporous resins.
Usage:
When using macroporous adsorption resin for separation and refining process, the general operating steps are: pre-treatment of macroporous adsorption resin - upper column of resin - upper column of drug solution - desorption of macroporous adsorption resin - cleaning and regeneration of macroporous adsorption resin. Due to the fact that each operating unit affects the separation effect of macroporous adsorption resin, the requirements for the refining process and separation technology of macroporous adsorption resin are relatively high
