Problems solved by technology

[0007] Therefore, in view of the fact that the existing single decolorizing agent cannot meet the needs of industrial vitamin purification and production, a new type of efficient decolorizing material is urgently needed to decolorize the vitamin solution; for this reason, the patent of the present invention proposes the use of activated activated carbon and activated silica gel Composite to make composite materials with different pore sizes, large specific surface area, and strong adsorption capacity for pigments in vitamins, so as to achieve selective adsorption and efficient decolorization of pigments in vitamins, so as to meet the production requirements for the preparation of high-purity vitamins

Abstract

The invention provides a method for preparing a composite material for removing vitamin C solution pigment, comprising the following steps: heating and activating activated carbon and silica gel for 4 to 6 hours at a heating temperature of 80 to 120°C, activated activated carbon and silica gel Silica gel is mixed in a mass ratio of 1:1. The invention also provides a composite material for removing pigment from vitamin C solution, which is obtained by using the preparation method of the above composite material. Activated carbon and silica gel adsorb pigments of different molecular weights in the vitamin C solution to achieve multiple adsorption decolorization effects. The present invention also provides a method for removing the vitamin C solution pigment, comprising the following steps: taking the above-mentioned composite material and adding it into the vitamin C solution, adding activated carbon and activated silica gel into the vitamin C solution to become a mixed solution, and The mixed solution was heated in a water bath. Compared with the existing unactivated single decolorizing agent, the decolorizing effect of this method is greatly improved.

Description

technical field [0001] The invention relates to a composite material for removing vitamin C solution pigment. [0002] The invention also relates to a preparation method of the composite material from which vitamin C solution pigment is removed. [0003] The invention also relates to a method for removing pigment from vitamin C solution. Background technique [0004] Vitamins are a class of low-molecular-weight organic compounds with different properties. They are called vitamins because of their biological functions. In recent years, people pay more and more attention to vitamins, especially knowing that some vitamins can prevent and treat cancer and coronary heart disease, so the research work on vitamins has been increased. When people study the biochemical functions of various vitamins, in addition to knowing their chemical characteristics and sources, it is more important that people have an increasing demand for high-purity vitamins that are beneficial to human healt...
