Problems solved by technology

These composite materials use mesoporous carbon as a matrix, directly infiltrate polymers such as polymethyl methacrylate and polystyrene into the pores of mesoporous carbon to obtain physically mixed composite materials, and use this composite material to absorb vitamins. Or water treatment, etc., the disadvantage is that the preparation of mesoporous carbon itself is relatively complicated, and it is not easy to produce in batches.
Moreover, polymethyl methacrylate directly penetrates into the matrix, and is not organically combined with the matrix, so there are problems such as poor stability.

example 1

[0030] Example 1: Adsorption of methyl orange by activated carbon / polyaniline composite

[0031] Weigh 5g of mesoporous activated carbon, add 100ml of 1mol / l hydrochloric acid solution, and carry out ultrasonic vibration for half an hour. Then add 1 g of aniline and continue shaking for half an hour. Prepare 2mol / l ammonium persulfate solution. Slowly add ammonium persulfate solution with a molar ratio of 1:1 to aniline using a dropping funnel. After the addition, continue to react in ultrasonic vibration for 2 hours. The resulting product is washed and dried.

[0032] Take by weighing 0.5g gained product, add it in the 12mg / l methyl orange solution of 50ml, under the stirring effect of magnetic stirrer, take a sample every 20 minutes, measure the methyl orange in the solution on 721 spectrophotometer The absorbance of the absorbance represents the content of methyl orange in the solution, and the concentration of methyl orange in the solution is calculated. A total of 8 ...

Abstract

The invention discloses methods for making conducting polymer modified active carbon, relating to a method for preparing compound materials. The invention discloses two methods for preparing conducting polymer modified active carbon and application thereof in the field of environment purifying materials. The methods are characterized in that under the condition of an ultrasonic vibration or a solid phase reaction, a conducting polymer monomer is subjected to in situ polymerization reaction on the surface of the active carbon to obtain the active carbon/conducting polymer compound materials. The conducting polymer modified active carbon prepared by the methods still keeps higher specific surface area of the active carbon, has functionalities from the conducting polymer and excellent absorption performance to metal ions and organic materials in a water solution, and is a novel compound material for processing water pollution and purifying environment.

Description

technical field [0001] The invention relates to a method for preparing composite materials, in particular to a method for preparing conductive polymer-modified activated carbon used for purifying industrial sewage or dye water.
