Advanced activated carbon extract and adsorption capacity

Activated carbon is a non-polar adsorbent, mainly used for the removal of pigment and the separation of water-soluble components such as amino acids, sugars and some water-soluble glycosides, he is one of the main methods for the separation of water-soluble components. Activated carbon column chromatography is characterized by easy raw material source, low price, large sample load, good separation effect, suitable for mass preparation separation. However, due to the production of activated carbon raw materials, preparation methods and specifications are different, its adsorption force is not as easy to control as silica gel, alumina. Up to now, there is no ideal method to determine the level of adsorption, which limits the wide application of activated carbon column chromatography.wholesale activated carbon pellet
one Source and preparation of activated carbon
Activated carbon according to its source is usually divided into plant carbon, animal carbon and mineral carbon three kinds, respectively, the use of wood chips or plant fiber, animal bones, coal and so on by high temperature carbonization. At present, the commonly used medical activated carbon and activated carbon chromatography with wood chips as raw materials, add zinc chloride in 700-800 by high temperature carbonization, activation, and by appropriate methods to remove impurities. Due to the presence of various metal ions in plants and the addition of zinc chloride in the production process, although it has been properly treated before leaving the factory, it is inevitable to contain trace metal ions, which should be paid attention to when used. Activated carbons used for chromatography generally fall into the following three categories.Medicinal or chemical pure activated carbon before leaving the factory after impurity treatment and metal limit inspection, can be used directly for chromatography. Industrial activated carbon is not processed by impurities before leaving the factory, often contains metal ions, affecting the separation effect, so it must be treated before use, its treatment methods are two.www.chinactivecarbon.com/
