离子交换树脂对铀的静态和动态吸附行为研究
Study of Ion Exchange Resin’s Static and Dynamic Adsorption Behavior for Uranium(Ⅵ)
摘要
Abstract
A Ф40 mm × 1200 mm adsorption device was used to simulate the actual urani-um hydrometallurgy process in industrial production,with the breakthrough curve got in an ion exchange adsorption fixed bed and the static adsorption experiment was carried out to measure equilibrium adsorption quantity under different concentration. Freundlich and Langmuir adsorption isotherm models are applied to fit experimental equilibrium data, which shows that both are suitable to describe the adsorption of ion exchange resin for ura-nium and the process of the adsorption of uranium is controlled by liquid film diffusion and hole diffusion together,and the dynamic adsorption capacity is about 1. 87 times that of the static adsorption capacity. Bohart Adams model and Wolborska model are carried out on the breakthrough curve fitting,of which the correlation coefficients are above 0. 92,the er-ror between resin adsorption capacity of model and Liquid method is small. This article puts forwar a point to explain the difference between the static adsorption and dynamic ad-sorption.关键词
