Description
Technical field
The present invention relates to a kind of preparation method of gac, particularly utilize the Amygdalus pedunculata nucleocapsid to prepare the method for gac.
Background technology
Gac is a kind of porousness carbonaceous material, and its inside has very flourishing pore texture and huge specific surface area, is widely used in sewage disposal and the air purification engineering.Along with the propelling of process of industrialization, the Application Areas of gac is broader.At present, some foodstuff productions (such as carbohydrate, fruit juice, vinegar, oils etc.) can produce phenolic compound in the process, the color of they and food, viscosity, smell is closely related, but when the excessive concentration of phenolic compound oxidizing reaction can occur, reduce the quality of product, can keep food stability and utilize charcoal absorption to remove phenolic compound, prolong the storage life of food.Gac can also be as support of the catalyst in addition, battery electrode, and the material of making electrical condenser also is applied at biomedical aspect as sorbent material simultaneously.
Traditional gac is to form as raw material adopts conventional physical method or chemical process to fire through two stages of carbonization-activation mainly with timber, coal etc. greatly.Gained gac specific surface area is generally 800-1000m
2/ g take micropore (＜2nm) as main, also comprise a small amount of mesopore (2-50nm) and macropore (〉 50nm), is applicable to adsorb the impurity of molecular weight.And the food decolouring, the gac that needs in the engineerings such as biomedicine is mainly used in the larger organic molecule of Adsorption molecular weight, and therefore traditional gac can not satisfy the demand in these fields.
Amygdalus pedunculata (Amygdatus) has another name called Padan's apricot, is commonly called as " fruit or seed of Szechwan Cherry " or " Nanking cherry ", is Rosaceae Amygdalus machaka, once is distributed widely in the areas such as northern Shensi, the Inner Mongol, Gansu, then because the desert is flooded with artificial destruction endangered.This seeds trunk is short and small, and well developed root system, its main root can reach more than 10 meter with entering, has the advantages such as strong adaptability, drought-enduring cold-resistant, Resistant, is the vanguard tree seed of afforestation and sand control afforestation.At present, North Shaanxi spread plantation Amygdalus pedunculata, in the processing later stage of fruit, often adopt the means of burning that nucleocapsid is processed, obviously cause greatly waste and the environmental pollution of resource, and this patent is recycled the preparation gac with the Amygdalus pedunculata nucleocapsid, has brought additional economic benefit when addressing the above problem.
There has been research to prepare the higher granule decoloration active carbon of absorption property with hard fruit shell; be that the Chinese patent application disclosed " granule decoloration active carbon and preparation method thereof " of CN 101054176A is although adopted the physical chemistry activation method to make the granulated active carbon of better performances such as publication number; but soak time reaches 8-12h, and energy consumption is large.
Summary of the invention
The object of the invention provides a kind of preparation method of Amygdalus pedunculata nucleocapsid gac.The iodine sorption value of prepared gac, methylene blue adsorption value, specific surface area and mesoporous possess stronger absorption property apparently higher than common gac.
For this reason, the preparation method of Amygdalus pedunculata nucleocapsid gac provided by the invention is:
