Impact of synthesized amino alcohol plasticizer on the morphology and hydrophilicity of polysulfone ultrafiltration membrane
In this work, polysulfone (PSF) ultrafiltration membranes with increased hydrophilicity were prepared using the amino alcohol plasticizer (AAP). The AAP was synthesized by the reaction of polyethylene glycol (PEG) and isatoic anhydride (IAH). Different molecular weight of PEG and IAH (molecular weig...

| 520 | |a In this work, polysulfone (PSF) ultrafiltration membranes with increased hydrophilicity were prepared using the amino alcohol plasticizer (AAP). The AAP was synthesized by the reaction of polyethylene glycol (PEG) and isatoic anhydride (IAH). Different molecular weight of PEG and IAH (molecular weight 163Da) were used for preparing the AAP. Asymmetric membranes were fabricated by blending these plasticizers in membrane casting solution. Formation of AAP was confirmed by FTIR and 1HNMR spectra of AAP. Characterization of membranes was done in terms of hydraulic permeability, pure water flux (PWF) and hydrophilicity. PWF was found to be increased from 29.3L/m2 h to 110.1L/m2 h and water contact angle also reduced from 72° to 62° for plain and AAP containing PSF membrane, respectively. The morphological and structural analysis of the membranes was done by scanning electron microscope and field emission scanning electron microscope. Permeation and rejection behavior of fabricated membranes was studied by Bovine serum albumin (BSA) solution. Maximum BSA rejection was increased by 20.5% for the modified membrane. FESEM images affirm that the pore size of the membranes decreased by the addition of AAP. PEG with molecular weight of 400Da based AAP gave best performance among all the membranes for each parameter. | ||

Impact of synthesized amino alcohol plasticizer on the morphology and hydrophilicity of polysulfone ultrafiltration membrane |
| abstract |
In this work, polysulfone (PSF) ultrafiltration membranes with increased hydrophilicity were prepared using the amino alcohol plasticizer (AAP). The AAP was synthesized by the reaction of polyethylene glycol (PEG) and isatoic anhydride (IAH). Different molecular weight of PEG and IAH (molecular weight 163Da) were used for preparing the AAP. Asymmetric membranes were fabricated by blending these plasticizers in membrane casting solution. Formation of AAP was confirmed by FTIR and 1HNMR spectra of AAP. Characterization of membranes was done in terms of hydraulic permeability, pure water flux (PWF) and hydrophilicity. PWF was found to be increased from 29.3L/m2 h to 110.1L/m2 h and water contact angle also reduced from 72° to 62° for plain and AAP containing PSF membrane, respectively. The morphological and structural analysis of the membranes was done by scanning electron microscope and field emission scanning electron microscope. Permeation and rejection behavior of fabricated membranes was studied by Bovine serum albumin (BSA) solution. Maximum BSA rejection was increased by 20.5% for the modified membrane. FESEM images affirm that the pore size of the membranes decreased by the addition of AAP. PEG with molecular weight of 400Da based AAP gave best performance among all the membranes for each parameter. |

Permeation and rejection behavior of fabricated membranes was studied by Bovine serum albumin (BSA) solution. Maximum BSA rejection was increased by 20.5% for the modified membrane. FESEM images affirm that the pore size of the membranes decreased by the addition of AAP. PEG with molecular weight of 400Da based AAP gave best performance among all the membranes for each parameter.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Plasticizer</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Hydrophilicity</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Polyethylene glycol</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Isatoic anhydride</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Polysulfone</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Purkait, M.K.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Yue, Xin-Zheng ELSEVIER</subfield><subfield code="t">Steering charge kinetics in W</subfield><subfield code="d">2019</subfield><subfield code="d">the official journal of the North American Membrane Society</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV002478420</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:522</subfield><subfield code="g">year:2017</subfield><subfield code="g">day:15</subfield><subfield code="g">month:01</subfield><subfield code="g">pages:202-215</subfield><subfield code="g">extent:14</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.memsci.2016.08.068</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">35.17</subfield><subfield code="j">Katalyse</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">58.50</subfield><subfield code="j">Umwelttechnik: Allgemeines</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">43.12</subfield><subfield code="j">Umweltchemie</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">522</subfield><subfield code="j">2017</subfield><subfield code="b">15</subfield><subfield code="c">0115</subfield><subfield code="h">202-215</subfield><subfield code="g">14</subfield></datafield><datafield tag="953" ind1=" " ind2=" "><subfield code="2">045F</subfield><subfield code="a">570</subfield></datafield></record></collection>
