Abstract
The invention discloses the preparation method of a kind of Caulis Sacchari sinensis leaf and Sugarcane peel. gac, it be by Caulis Sacchari sinensis leaf and Sugarcane peel. cleaning, dry, pulverize and sieve after, by a certain percentage activator, additive are mixed with into activation solution, mix with a certain proportion of raw material again, after leaving standstill certain hour, the certain hour of charcoal activation at a certain temperature, takes out, cools, utilize clear water rinsing to certain pH value, dry and obtain Caulis Sacchari sinensis leaf gac.Positively effect of the present invention is: prepare gac by the method, not only there are a large amount of stable raw material sources, also can reduce the energy consumption of 10 ~ 35%, save the water consumption of 27.3% ~ 85.8%, yield rate and the absorption property of product are high, wherein, iodine sorption value is 1.3 ~ 1.6 times of national Wooden activated carbon for water purification first grade standard, has boundless industrial applications prospect.
Description
Technical field
The present invention relates to a kind of preparation of gac, specifically a kind of Caulis Sacchari sinensis leaf and Sugarcane peel. of utilizing prepares the method for gac for raw material.
Background technology
Gac has flourishing pore texture, abundant surface functional group, huge specific surface area and very strong adsorptive power, and physics and chemistry stable in properties, there is certain physical strength, water insoluble and organic solvent, be therefore widely used in the fields such as chemical industry, environmental protection, food, medicine, military project.
At present, gac preparation is main is that raw material is activated obtained with timber, brown coal, pitch etc.Because timber cost is high, resource-constrained; Coal mass active carbon kind is many, and price is low, and its raw material is Nonrenewable resources, and there is the defects such as ash content is high, impurity is many.Therefore, new starting material such as stalk, shell etc. is utilized to prepare the development trend that gac is this field, not only can meet the growing gac market requirement, also can solve a large amount of agricultural wastes simultaneously and burn the problem such as the wasting of resources and atmospheric pollution brought.But there is the defects such as energy consumption is high, absorption property is poor, yield is low when preparing gac in most of agriculture and forestry organic waste material, is not easy to realize suitability for industrialized production.
Summary of the invention
The object of this invention is to provide a kind of Caulis Sacchari sinensis leaf and Sugarcane peel. of utilizing and prepare the method for gac for raw material, this preparation method is simple, and cost is low, and energy consumption is low; Obtained gac has the advantages that yield is high, absorption property is good.
The preparation method of a kind of Caulis Sacchari sinensis leaf of the present invention and Sugarcane peel. gac, comprises the steps:
(1) Caulis Sacchari sinensis leaf and Sugarcane peel. cleaning are removed surface dirt foreign material, dry at 40 ~ 80 DEG C, then pulverize, grinding particle size is 8 ~ 200 orders;
(2) soaked in activation solution by step (1) gained raw material, soak time is 1 ~ 100h, and the mass ratio of activation solution and raw material is 1 ~ 12:1; After immersion, at temperature is 300 ~ 1000 DEG C, activation, soak time are 10 ~ 200min;
Described activation solution is 40 ~ 200 ︰ 1 by activator and additive by weight, and being mixed and made into total mass concentration is 30 ~ 50
wtthe mixed solution of %;
Described activator, by one or more in primary ammonium phosphate, ammonium hydrogen phosphate, ammonium phosphate, ammonium acetate and ammonium sulfate, is mixed by identical weight ratio;
Described additive, by one or more in nickelous nitrate, cerous nitrate, cupric nitrate and lanthanum nitrate, is mixed by identical weight ratio;
(3) be 5.0 ~ 9.0 by the raw material clear water rinsing after the activation of step (2) gained to pH value, reclaim waste liquid simultaneously;
(4) by step (3) gained raw material 40 ~ 200 DEG C of oven dry, drying time is 20 ~ 600min, obtains gac.
Positively effect of the present invention is: prepare gac by the method, not only there are a large amount of more stable raw material sources, also can reduce the energy consumption of 10 ~ 35%, save the water consumption of 27.3% ~ 85.8%, yield rate and the absorption property of product are high, wherein, iodine sorption value is 1.2 ~ 1.9 times of national Wooden activated carbon for water purification first grade standard, has boundless industrial applications prospect.
