Abstract

The invention discloses a preparation method for jute-based active carbon, and the method comprises the following steps of: weighing jute fibres or crushed jute stem materials, cleaning and drying, soaking in a beaker filled with a 3-5mol / L phosphoric acid solution, boiling for 3-10 hours in a water bath, adequately penetrating an activating agent into the fibres, then taking out and drying; placing in a vacuum tubular high-temperature sintering furnace, activating to 400-500 DEG C in a nitrogen atmosphere, insulating for 1-3 hours, or placing in a columnar quartz tube, placing in a microwave device, and performing a microwave irradiation reaction with a microwave irradiation power of 100-700 W and an irradiation time of 5-30 minutes in the presence of nitrogen used as protective gas; and cooling to a room temperature, then taking out, acid-washing and repeatedly water-washing until the pH is 6-7, and then drying to obtain the jute-based active carbon. The jute-based active carbon prepared by the method has the advantage of being high in methylene blue adsorption value and activation yield.

Description

technical field

[0001] The invention relates to a preparation method of jute-based activated carbon, belonging to the technical field of activated carbon production. Background technique

[0002] Activated carbon is a carbonaceous adsorption material with rich pore structure and huge specific surface area. It has the characteristics of strong adsorption capacity, high mechanical strength, good chemical stability, and convenient regeneration. It is widely used in industry, agriculture, transportation, medicine and health. , national defense, environmental protection and other fields. In recent years, with the increasing requirements for environmental protection, the demand for activated carbon at home and abroad has been increasing year by year.

[0003] The raw materials for traditional activated carbon preparation are mainly wood and coal. Due to the limited and decreasing domestic forest resources and the high price of coal, it is an urgent problem to be solved in the fi...
