摘　　要：在318K和pH=8.0条件下,利用不可逆热力学方法研究了染料和硝酸钠混合电解质溶液在压力下通过水合氧化锆-聚丙烯酸动态膜[dynamically-formedzirconium(Ⅳ)hydrous.xide-polyacrylatemem-brane]的迁移性质,既得到了实用迁移系数(practicaltransportcoefficient):Lp,水透过系数(hydrodynamicpermeability),σ截留系数(reflection)和ω溶质透过系数(solutepermeability),又讨论了染料浓度对迁移性质的影响.The nanofiltration of dye-NaNO3 aqueous solutions at pH 8.0 using a dynamically-formed zirconium hydrous oxide - polyacrylate membrane has been investigated at 318 K. The practical transport coefficients for hydrodynamic permeability（ Lp ）,reflection （σ）,and solute permeability （ ω ） ,are calculated from the nanofiltration results using irreversible thermodynamics equations. Effect of dye concentration is interpreted in term of solute- membrane interaction.
