Nira Potential as Membrane Preparation Materials

Abstract

The cellulose acetate membrane based on nira (coconut flower water) was successfully synthesized by phase inversion method. This research was conducted through some steps which were microbial cellulose synthesis, cellulose acetate synthesis, synthesis of cellulose acetate membrane with PEG additive and characterization of membranes.  The characterizations were flux, rejection, tensile strength, and pore sizes. The result showed that cellulose acetate membrane flux were 27.52 L/m².h and rejection of dextran T-500 were 63.30 %. The tensile strength was 1,6 N/m² and the pore sizes was 0.25 – 0.5 µm which were ultrafiltration membranes
