Abstract

The invention belongs to the field of activated carbon, and relates to a preparation method for preparing functional activated carbon through carbonization and activation of enteromorpha and application of the functional activated carbon. An activating agent is supported on enteromorpha powder through a one-step method, then enteromorpha-based activated carbon is obtained through high-temperature firing, grinding and washing, then an antibacterial agent is added, and the functional activated carbon is obtained. And the enteromorpha-based antibacterial active carbon material with antibacterial ability is obtained through sufficient mixing and ultrasonic in-situ growth. The antibacterial activated carbon prepared by the method is large in specific surface area, rich and uniform in gap and good in mechanical property; the antibacterial broad-spectrum property is strong, the sterilization rate is high, drug resistance is not generated, and the composition is relatively safe to a human body and the environment; the application is wide, and large-scale quantitative production in the future market is facilitated. The activated carbon with the functions of adsorption deodorization and water quality purification can also be prepared, and compared with other activated carbon, the activated carbon is developed in pores, large in specific surface area, high in adsorption capacity, high in desorption speed, low in cost price and relatively high in mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of activated carbon, and in particular relates to a method for preparing functional activated carbon through carbonization and activation of enteromorpha and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The "green tide" caused by Enteromorpha often breaks out, which has seriously affected and damaged the natural environment, economy and seawater production and processing, and the urban environment has also increased pollution. Studies have found that Enteromorpha has many application values. Enteromorpha contains a large amount of organic components. After drying, its carbon content ac...
