活性炭对诺氟沙星吸附效果的研究

The Research of Adsorption Effect of Activated Carbon for Norfloxacin

文章以诺氟沙星吸附量为指标,采用硝酸改性和高温热处理两种改性活性炭对诺氟沙星进行吸附研究。结果表明:活性炭对诺氟沙星的吸附主要发生在中孔,中孔孔容和中孔比表面积是影响吸附的主要因素;同时活性炭表面碱性基团量越多,吸附效果越好。硝酸改性不利于活性炭对诺氟沙星的吸附;高温热处理则有利于活性炭的吸附。

In the paper, based on the adsorption quantity of norfloxacin as an index, the adsorption effect of norfloxacin on activated carbons of nitric acid modified and high temperature heat treatment is studied. Results show that adsorption of the activated carbon for norfloxacin occurs mainly in the mesopore, the pore volume and specific surface area of mesopore is the main factoe affecting adsorption; the more amounts of alkaline groups on activated carbon surface, the adsorption effect is better. Nitrate modification of activated carbon is bad for the adsorption of norfloxacin; high temperature heat treatment of activated carbon is conductive to the adsorption of norfloxacin
