[Poli(5-bromo-1-benzofuran-2-il)(fenil)-O-metakrilketoksim-ko-2- (4asetilfenoksi-2-oksoetil-2 metakrilat] – [Poli(metil metakrilat-ko-etil akrilat)]/ Poli(vinil alkol)-Selüloz Membranların Hazırlanması ve Fe(III)’ün Sudan Arıtımında Kullanılması

Bu araştırmada; yeni $lbrack1/3;(frac mm;);poli(5-bromo-1-benzofuran-2-il)(fenil)-O-metakrilketoksim-ko-2-(4asetilfenoksi-2-oksoetil-2;metakrilatrbrack–lbrack2/3;(operatorname{?};operatorname{?};);(poli(metil;metakrilat-ko-etil;akrilat)rbrack/;poli(vinil;alkol)$ selüloz membranları üretilmiş ve SEM ile karakterizeedilmiştir. Bu membranlar Fe(III) iyonlarının sulu çözeltilerden ultrafiltrasyonla ayrılmasında kullanılmıştır. pH’ın (3, 4, 5), çözeltiderişiminin (0,30x$10^{-4}$ M, 0,50x$10^{-4}$ M) ve basıncın (30psi, 40 psi, 50 psi) sulu ortamdaki Fe(III) iyonlarının tutulma ve akıya olanetkileri çalışılmıştır. Elde edilen membranların 50 psi basınca kadar sorunsuz olarak kullanılabileceği bulunmuştur.

Preparation of $lbrack1/3(frac mmPoly(5-bromo-1-Benzofuran-2-yl)(phenyl)-O-methacrylketoxime-co-2-(4-acetylphenoxy-2-oxoethyl-2-;methylacrylate)rbrack-;lbrack poly(methyl;methacrylate-co-ethyl;acr-Cellulose Membranes and their Using in Treat

In this study; new $lbrack1/3(frac mmPoly(5-bromo-1-Benzofuran-2-yl)(phenyl)-O-methacrylketoxime-co-2-(4-acetylphenoxy-2-oxoethyl-2-;methylacrylate)rbrack-;lbrack poly(methyl;methacrylate-co-ethyl;acrylate)rbrack/;poly(vinyl;alcohol)$ -cellulose membranes were prepared and characterized by SEM. The using of these membranes for the separation of Fe (III) ions from aqueous solutions by ultrafiltration was investigated. The effects of pH (3, 4, 5), concentration of solution (0,30x$10^{-4}$ M, 0,50x$10^{-4}$ M) and pressure (30 psi, 40 psi, 50 psi) on the retention and flux were studied. It has been found that these membranes can be used as smoothly as to 50 psi pressure.
