Sintesis Membran Silika Berbahan Baku Sekam Padi : Variasi Komposisi Poly Ety…

Membrane is a selective and semipermeable layer that lies between two phases, namely feed phase and permeate phase. Membrane synthesis using silica with phase inversion method. The purpose of this research were to make membranes of polysulfone for waste Rhodamin B with 0; 0,15; 0,30; dan 0,45 gram by weight PEG and operating pressure of 1, 3, and 5 bars. This research produced porous membrane. …
