Removal of Silica in Wastes With Methyl Cellulose Composite Membranes
Abstract In this study, experiments were carried out for composite membrane synthesis with m-phenylenediamine (MPD), hydroxyethyl methacrylate (HEMA) and methyl cellulose (MS) by changing process parameters (methyl cellulose ratio, synthesis temperature, stirring time, oven temperature). Taguchi Method, an optimization method for production, was applied to 4 levels 4 parameters. The silica solution was passed through the produced composite membrane, and the filtering property of the membrane for different periods was examined. Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) were used for characterization of composite membranes. Shore A test was performed to determine the mechanical strength of composite membranes. The amount of silica in membranes obtained because of the silica treatment was determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) analysis. As a result, it was seen that the composite membranes produced could be evaluated in the treatment of wastewater containing silica.
