| Abstract: | The retentiveness of microfiltration membranes based on crystalline silicon dioxide with an average pore size of 3 μm with respect to ferric iron ions Fe(III) is studied. A correlation between the state of Fe(III) in water solutions and the degree of retention, as well as the membrane surface origin and structural properties, is found. A comparative assessment of the retentiveness of the microfiltration ceramic and ultrafiltration polyamide membranes—with an average pore size of 7.8 nm—with respect to Fe(III) ions is made. |
