Abstract

The invention discloses a method for removing antibiotic-sulfadiazine in water through activated carbon fiber adsorbent. The method comprises the steps that the activated carbon fiber adsorbent is placed into water containing antibiotic-sulfadiazine according to the certain placing amount, vibration adsorption is carried out at set temperature, the treated water is filtered after vibration adsorption is finished, activated carbon fiber adsorbing antibiotic-sulfadiazine is separated from the treated water, and therefore the antibiotic-sulfadiazine in the water is removed. The method can effectively remove antibiotic-sulfadiazine in water, and meanwhile has the advantages of being high in removal efficiency, resistant to corrosion and heat, beneficial to separation and the like. The absorbent preparation process is simple, low in cost, low in energy consumption and quite good in application prospect. The method for removing sulfadiazine through the activated carbon fiber is low in energy consumption, economic and environmentally friendly, has the certain industrial development potential and provides a new thought for removing sulfadiazine.

Description

technical field [0001] The invention relates to a method for removing organic pollutants in water bodies, in particular to a method for removing antibiotic-sulfadiazine in water bodies by physical adsorption, which is applied to the technical field of water body protection and treatment for the removal of sulfonamide antibiotic residues in polluted water bodies . Background technique [0002] Activated carbon fiber is a kind of porous fibrous adsorption material prepared by high-temperature carbonization and activation of organic fibers. It has the characteristics of a certain amount of oxygen-containing functional groups. These characteristics make activated carbon fibers have excellent adsorption properties, have a large adsorption capacity and fast adsorption speed for gas and liquid phase molecules, and can efficiently remove pollutants in solutions or gases. In addition, activated carbon fiber can also be made into shapes such as yarn, thread, cloth, felt, etc., which...
