Abstract
The present invention relates to a kind of preparation method of activated carbon, using pecan shell as raw material, sieved after pecan shell is crushed, be then added in phosphoric acid solution and soak 16 24h, the weight ratio of pecan shell and phosphoric acid solution is 1:36, filtering；The filter residue being filtrated to get is placed in heat-activated in Muffle furnace, room temperature is subsequently cooled to, obtains activator；By activator pickling, then neutrality is washed to, finally sieves, produce.The inventive method technique is simple, and it is not using timber as raw material, and using discarded object pecan shell as raw material, and extensively, cost is low, and protects ecological environment, and obtained adsorption effect of activated carbon in water is good for raw material sources.
Description
Technical field
The present invention relates to a kind of preparation method of activated carbon, belong to technical field of fine.
Background technology
Activated carbon be it is a kind of there is abundant pore structure and the carbonaceous sorbing material of huge specific surface area, it its have energy of adsorption
Power is strong, chemical stability is good, mechanical strength is high, and can facilitate the features such as regenerating, and is widely used in industry, agricultural, national defence, friendship
The fields such as logical, medical and health, environmental protection, its demand is improved with social development and living standards of the people, in rising year by year
Trend, the especially increasingly raising recently as environmental protection requirement so that the demand of domestic and international activated carbon is increasingly
Greatly, increase year by year.
At present, use timber for raw material activated carbon, raw material is somewhat expensive, production technology is more complicated more, and this undoubtedly will
A large amount of forests are caused to be cut down, heavy damage is ecological.Therefore it is very necessary to find cheap raw material and simple production technology
's.
The content of the invention
There is provided a kind of activated carbon for the deficiency existed present invention aim to address the preparation technology of activated carbon in the prior art
Preparation method, it is not using timber as raw material, and cost is low, technique is simple, and obtained adsorption effect of activated carbon in water is good.
Technical scheme
A kind of preparation method of activated carbon, comprises the following steps：
(1) using pecan shell as raw material, sieved after pecan shell is crushed, be then added in phosphoric acid solution and soak 16-
24h, filtering；
(2) filter residue being filtrated to get is placed in heat-activated in Muffle furnace, is subsequently cooled to room temperature, obtain activator；
(3) by activator pickling, then neutrality is washed to, finally sieves, produce；
In step (1), the weight ratio of the pecan shell and phosphoric acid solution is 1:3-6.
Further, in step (1), the concentration of the phosphoric acid solution is 35-55wt%.
Further, in step (1), the sieving was 30 mesh sieves.
Further, in step (2), the activation temperature is 200-500 DEG C, and the time is 30-120min.
