Problems solved by technology
When the water content reaches 16% to 18%, the adsorption of silica gel will become very poor, so silica gel must be activated at high temperature before use. Silica gel can adsorb both polar compounds and non-polar compounds, but poor selectivity
For low-polarity compounds such as coenzyme Q10, the adsorption capacity is insufficient and the adsorption efficiency is low, so the amount of silica gel used is relatively large
In addition, the silica gel particles are fine and the pore size is small. In column chromatography separation, the mass transfer rate is low and the liquid flow resistance is large, which will affect the production efficiency.

Embodiment Construction
[0018] Below in conjunction with embodiment the present invention is described in further detail.
[0019] Preparation of composite adsorbent materials:
[0020] 1. Sodium alginate with a viscosity of 200±20mpa.s is dissolved in water to make a concentration of 3-4wt.%. Soak a commercially available melamine sponge (10cm in diameter and 20cm in thickness) in viscous in the solution for 1 to 2 hours;
[0021] 2. After taking it out, quickly put it into the sulfuric acid solution with pH=3~4 and soak it for 2~3 hours, then put the compound into clean water and rinse it at room temperature for 4~5 hours;
[0022] 3. Place the material in a ventilated place at room temperature to dry naturally. After 3 to 4 days, the inside of the compound will form as figure 1 The macroporous structure shown, through 6 preparation experiments, is determined by gravimetric method. Chitosan in the material accounts for 52-58wt.% range, and the specific surface area of the material measured by a...

Abstract
The invention relates to a composite polymer adsorption material and a preparation method thereof. Utilizing the unique three-dimensional skeleton structure of the commercialized melamine sponge, the sodium alginate aqueous solution is introduced into the sponge and solidified under acidic conditions, and then the water in the alginic acid is removed by natural drying, finally forming a unique three-dimensional macroporous system , in which the melamine sponge plays the role of mechanical stability and support, while the alginic acid is fully dispersed to form a multi-layer penetrating film, and the surface of the alginic acid is covered with a layer of amphiphilic polymer containing long chains of fat through the interaction of hydrogen bonds. The adsorption efficiency of coenzyme Q10 is significantly improved. The content of alginic acid in the composite material is in the range of 52-58wt.%, and the specific surface area is in the range of 52.6-61.4m2 / g. The composite adsorption material can be used as an integral adsorption column. It is used to extract coenzyme Q10 and achieve better results. The advantages of this material are: strong adsorption capacity, easy operation, and the material can be recycled for many times, reducing costs and improving production efficiency.
