摘要:
膜的结构参数(细孔半径、孔隙率与膜厚之比)与荷电特性参数(荷电密度)是纳滤膜最重要的特征参数,也是影响膜分离性能的关键因素.通过卷式纳滤膜NF90和NF270膜的透过实验,应用Spiegler-Kedem方程结合透过实验数据求得膜的反射系数和溶质透过系数,进而应用细孔模型和TMS模型求得NF90和NF270膜的细孔半径分别为0.46 nm和0.60 nm,孔隙率与膜厚之比分别为0.99×105m-1和1.14×105m-1,荷电密度随膜面电解质浓度的增大成线性增大,可分别表示为X(NF90)=54.89Cm + 175.85与X ( NF270) = 6.20Cm + 6.55.
Abstract:
S tructura l param e ters( m embrane pore rad ius and the ratio o fm em brane poro sity tom em brane thickness) and the param eters o f charge characterstics ( Charge density ) are the m ost im portant characteristic param eters of nano filtration m em brane, and are a lso key fac to rs wh ich have an im po rtant influence on separation pe rfo rm ance. Perm eation experim ents o f aqueous solution of neutra l so lutes and electro ly tew ith NF90 and NF270 spiralm embranes w ere conducted and m em branes param e ters ( reflec tion coeffic ient and so lute pe rm eab ility) w ere obtained from Spieg ler-Kedem equation, then structura l param eters and the effective charge densities w ere estim a ted using the ster ic-h indrance pore ( SH P) model and TM S m ode l respectiv ely. M em brane po re radius o fNF90 and NF270 w ere about 0.46 nm and 0.60 nm respective ly, the ra tio of membrane po rosity to m em brane th ickness w ere about 0.99× 105 m - 1 and 1.14 × 105 m - 1 respective ly, Charge density cou ld be determ ined byX ( NF90) = 54.89Cm + 175.85 and X ( NF270) = 6.20Cm + 6.55 respectively.
