摘要
研究D201树脂吸附钒(V)的过程。结果表明,pH值对D201树脂吸附钒的影响很大,与钒在溶液中的赋存状态有关。测得吸附热力学参数ΔH=8.11kJ.mol-1,ΔS=34.63 J.mol-1.K-1,ΔG298=-2.21 kJ.mol-1。动力学研究表明吸附交换速率主要受液膜扩散控制,等温吸附遵循Freund lich和Langmu ir曲线。
The adsorption process of vanadium(V) with D201 resin is investigated.The results indicate that the adsorption of D201 resin for vanadium(V) is remarkably influenced by pH,since it is related with the condition of vanadium in solution.The adsorption parameters of thermodynamic are ΔH=8.11kJ·mol-1,ΔS=34.63J·mol-1·K-1,ΔG298=-2.21kJ·mol-1,respectively.Dynamics calculation indicates that the exchange-adsorption rate is mainly controlled by particle diffusion.The sorption behavior of D201 resin for vanadium(V) o...
