Abstract
The present invention provides a magnetic FeOnanosphere with PNH surface modification and application thereof in water treatment. First, 2,2-bipyridyl-5,5'-dicarboxylic acid is reacted with thionyl chloride to obtain 2,2-bipyridyl-5,5′-diacid chloride; then 2,2-bipyridyl-5,5′-diacid chloride and 1,4,8,11-tetraazacyclotetradecane react in the presence of triethylamine to obtain a polynitrogen heterocyclic polymer; the polynitrogen heterocyclic polymer is added into an aqueous solution with iron salt to obtain a magnetic FeOnanosphere with PNH surface modification which has strong light absorption ability, which improves its ability to catalyze in degradation of tetracycline under visible light, so that the pollutants are removed from water.
