Removal of heavy metals from aqueous solutions using new polymer membranes by different filtration techniques.

In this study seperation of Fe(III) and Co(II) ions from aqeuous solutions was investigated for absence and presence of complex. Alginic acid polymer was used as complexing agents. Poly(methyl methacrylate-co-ethyl acrylate) covered on poly(vinyl alcohol)/cellulose and poly(methyl metacrylate-co-ethyl acrylate) covered on [1/3(m/m Poly(5-bromo-1-Benzofuran-2-yl)(phenyl)-O-methacrylketoxime-co-2-(4-acetylphenoxy-2-oxoethyl-2-methylacrylate)] composite membranes were used in the filtration of Fe(III) ions from aqueous solution for absence of complex The effects of content of membranes, pressure, pH and concentration of solution on the retention and flux were studied. Poly[(methyl methacrylate-co-ethyl acrylate)] covered on poly(vinyl alcohol)/cellulose composite membranes were used in the filtration of Co(II) ions for absence of complex. The effects of content of membranes, concentration of solution, pH and pressure on the retention and flux were studied. Poly[methyl methacrylate-co-ethyl acrylate] covered on poly (vinyl alcohol)/Cellulose composite membranes were used in the filtration Fe(III) and Co(II) ions from aqueous solution for presence of alginic acid. The effects of content of membranes, concentration of solution, pH and pressure on the retention and flux were studied. In this study; the best retention were found as 94,20 % by using 0,75 % (m/v) [Poly(methyl methacrylate-co-ethyl acrylate)] covered on 0,75% (m/v) poly(vinyl alcohol)/celluse 2 composite membranes at pH of 4, concentration of 0,5×10-4 M Fe(III), pressure of 30 and stirred velocity of 400 rev/min in the presence at alginic acid.
