C/NiFe2O4 composite material was prepared by sol-gel method using glutinous rice as raw material of carbon. The structure, micro-morphology and adsorptive properties of acid fuchsin were studied. The nanoparitilce C/NiFe2O4 synthesized under the condition 450℃, 6h is 20nm and disperse homogeneously. It was found that the best adsorption condition was pH 5 and the remove rate can reach 88% in 10min. The remove rate of composite material was higher than sigle phase carbon and NiFe2O4, this mean that composition material can imporve removal rate effectively.
