Every field.The raw material of domestic production active carbon is mainly wooden resource, coal resources etc. at present, and the forest reserves are very nervous,
The usually resources such as wood-curing waste or coconut husk, shell are just used to produce active carbon；The coal reserves of China is although larger,
But it is suitble to the fat coal for preparing the low impurity of active carbon few in China's reserves；But the currently, waste of domestic all trades and professions
Yield is huge, and processing cost is high, if the waste for preparing active carbon will be suitble to be used to prepare active carbon, can not only reduce life
Cost is produced, fixed-end forces expense is reduced, moreover it is possible to reduce the consumption of forest, coal resources, protect environment and natural resources.
Papermaking is national pillar industry, and yield is huge, while needing a large amount of primary timber, therefore the recycling benefit of waste paper
With the felling that can reduce the forest reserves, there is the meaning of reality for the circulation of ecological environment.Carton is usually with having used
What the paper crossed was prepared again after deinking.Waste scrap carton is common domestic refuse, especially double 11 shopping sections
Later, while many people chop hand and buy, carton that pile up like a mountain is also at troubling problem.Therefore, it finds
A kind of utilization ways of novel waste scrap carton can effectively handle the waste scrap carton of enormous amount or be translated into high attached
Value added product lives to us or national environmental protection cause is all meaningful.
Summary of the invention
The purpose of the present invention is to provide a kind of method for preparation of active carbon based on waste scrap carton, utilize domestic refuse paper
Case prepares duct prosperity, and the high active carbon of specific surface area had not only solved waste pollution environmental problem, but also generated huge economy
Benefit.
The technical proposal for solving the technical problem of the invention:
The present invention is using waste scrap carton as raw material, successively by processing steps such as litter decoration degradation treatment, activation, post-processings, finally
It obtains aniline absorption and uses absorbent charcoal material.

(1) degradation treatment: by litter decoration: 5 ~ 10 g litter decoration crushed and 10 ~ 20 g activators are dispersed in 200 mL water
In, 6 h of stirring are until carton fully degrades and obtains paper pulp；
(2) dry: 12 h of oven drying by the paper pulp of paste at 110 DEG C；
(3) it carbonizes and activates: the paper pulp after drying being placed in tube furnace, under nitrogen or argon atmosphere, in 800 ~ 900 °C
Under, 2 h are kept the temperature, is carbonized and is activated；
(4) washing and drying treatment: Carbon Materials after successively cleaning activation with dilute hydrochloric acid and water, until the pH of filtrate and the pH value phase of water
Together, then through 90-110 DEG C it is dried, absorbent charcoal material is made.
The specific surface area that the present invention prepares active carbon is up to 985 ~ 1320 m2/ g has preferable absorption property.
The present invention has following technical advantage compared with prior art:
(1) present invention uses house refuse litter decoration for raw material, and cost of material is extremely low, environment can also be protected not to be contaminated
Considerable economic benefit is produced again；
(2) present invention makes full use of the features such as lignocellulosic is easy to carbonization-activation in litter decoration, is arrived by carbonizing, activating a step
Position, institute's preparing active carbon have hierarchical porous structure, and it is preferably to adsorb that large specific surface area, which has adsorption capacity well to aniline,
Material；
(3) step of the present invention is few, easy to operate, and low energy consumption, has a good application prospect.
