The bsa rejection increases as / decreases . the hydrophilicity of the surface of pvdf hollow - fiber membranes has been greatly improved and the antifouling ability increased obviously Pvdf基膜表面引入pamps长链分子或者pamps凝胶层,亲水性大为改善,抗污染能力明显提高。
The crosslinking system was : [ mbaa ] = 0 . 03 , 0 . 06 , 0 . 09mol / l , [ k2s2o8 ] = 0 . 0075 mol / l , t = 60 c , t = 40 ~ 60min . the existence of pamps gel layer on the surface of composite membrane was confirmed by ftir and sem 通过傅立叶红外光谱( ftir )分析和扫描电子显微镜( sem )的观察,证实了pvdf基膜表面pamps凝胶层的存在。
Peo can be completely intercalated into the interlayer of v2o5 xerogel in form of amorphous state at x = 0 . 5 , whereas partial peo can not be intercalated into v2os xerogel interlayer and exists outside of v2o5 xerogel interlayer in form of crystalline state at x = l , 2 当x为0 . 5时, peo的嵌入较完全,在层间以非晶态形式存在;当x = 1 、 2时,部分peo未能嵌入氧化物干凝胶层间而存在于其主体之外,以晶态形式存在。
Peo can be completely intercalated into the interlayer of v2o5 - moo3 xerogel in form of amorphous state at x 1 , whereas partial peo can not be intercalated into v2o5 - moo3 xerogel interlayer and exists outside of v2o5 - moo3 xerogel interlayer in form of crystalline state at x = 2 当x约为1时, peo的嵌入较完全,在层间以非晶态形式存在;当x = 2时,部分peo未能嵌入氧化物干凝胶层间而存在于其主体之外,以晶态形式存在。
