Preparation of Porous Nano Barium Ferrite and Its Adsorption Properties on Uranium
摘要
Abstract
The porous nano barium ferrite was made of Fe(NO3)3 and Ba(NO3)2 as raw materials, CTAB as surfactant by method of sol-gel and self-propagating combustion. The composition, morphology and magnetic properties of nano-rod barium ferrite were characterized by XRD, SEM and vibrating sample magnetometer. The adsorption properties of porous nano barium ferrite on uranium were studied with static adsorption and the effects of pH, adsorption temperature and oscillation time on adsorption properties were discussed. The results indicate that the average particle size of porous nano barium ferrite is 45-65 nm, the saturation magnetization and coercivity are 62. 83 emu/g and 5 481. 0 Oe, respectively. Under the condition of the porous nano barium ferrite amount of 0. 02 g, pH of 6, adsorption temperature of 25 ℃ and oscillation time of 30 min, the adsorption capacity of uranium on the porous nano barium ferrite reaches 921 μ/g.关键词
