摘    要:利用多羟基螯合树脂的结构特性,详细研究了多羟基螯合树脂对Fe3+、Co2+两种金属离子的吸附容量、等温吸附等静态吸附性能.结果表明,在适当的温度下,在HAC-NaAC体系中,树脂对两种离子都具有较强的吸附能力,树脂对上述2种离子的交换动力学符合Boyd G.E.方程,即交换由液膜扩散控制,且树脂对两种金属离子的吸附可用Freundlich等温吸附方程来描述.

关 键 词:多羟基螯合树脂  吸附  金属离子

Abstract:The static absorption properties of the chelating resin for Fe(Ⅲ), Co(Ⅲ)such as capacity, dynamics and isotherm absorption were studied by using the structural characteristics of polyhydroxy chelating resins.The results indicated tha: This resin had higher absorption capacity for Fe(Ⅲ), Co(Ⅲ) under appropriate temperature and in the HAC-Na AC system, the resin had good absorption capacity for Fe(Ⅲ), Co(Ⅲ), the equilibrium absorption data could be fitted to a Freundlich isotherm under the range of conditions studied. The adsorption of Fe(Ⅲ), Co(Ⅲ)ions on the resin were found to be a spontaneously endothermic process. Kinetic analysis showed that the absorption rates weremainly governed by liquid film diffusion.
Keywords:polyhydroxy chelating resin  absorption  metal ions
