Photocatalytic membrane was successfully prepared using an efficiently high surface area TiO2 catalyst, dispersed into polyacrylonitrile matrix. The catalyst was directly synthesized using titanium triisopropanolamine as a precursor. The membranes were characterized using FT-IR, TGA, SEM and their photocatalytic performance tested, viz. stability, permeate flux and photocatalytic degradation of...

Polyamidoxime chelating resin was obtained from polyacrylonitrile (PAN) grafted starch. The nitrile groups of the starch-grafted polyacrylonitrile (St-g-PAN) were converted into amidoximes by reaction with hydroxylamine under basic conditions. The synthesized graft copolymer and polyamidoxime were characterized by FTIR, TGA and elemental microanalysis. Metal chelation of the polyamidoxime resin...

8-Hydroxyquinoline immobilized on polyacrylonitrile hollow fiber membrane was synthesized and used for the preconcentration of rare earth elements (REEs) and the separation of the matrix in seawater prior to their determination by inductively coupled plasma mass spectrometry (ICP-MS). Both the capacity and chemical stability of the modified polyacrylonitrile hollow fiber membrane have been eval...

cellulose was modified by polystyrene (ps) and polyacrylonitrile (pan) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. for this purpose, first, the graft polymerization of styrene (st) onto cellulose fibers was performed by using suspension polymerization and ...

In this paper, polyacrylonitrile PAN - titania TiO2 electrospun nanofiber PAN/TiO2 nanofiber was prepared via a facile electrospinning method. The characteristics of the PAN/TiO2 nanofiber were investigated using SEM and FTIR. The nanofiber showed retained nanofiber structures and high photocatalytic efficiency under UV light for the degradation of Direct Red 80 DR80 and Direct Red 23 DR23 in w...

original article   electrospun nanofibrous filter media have attracted considerable attention in the last decade. the present study aimed to develop the electrospun pan (polyacrylonitrile) filter media through experimental investigations for application in high-performance air filters. for this purpose, an experimental design was proposed to assess the effect of electrospinning process conditio...

polyacrylontrile synthesis, via atom transfer radical polymerization, is studied in various initiator concentrations, transitional metal catalyst and different concentrations of cubr2. the variations of monomer conversion and the lin-earity of semi-logarithmic kinetic profile which is the evidence of living polymerization and constant radical concentration in the reaction medium, were revealed ...
