PEMBUATAN MEMBRAN KOMPOSIT KITOSAN-PVA DAN PEMANFAATANNYA PADA PEMISAHAN LIMBAH PEWARNA RHODAMIN B

Edit
Abstract: The manufacturing of chitosan-PVA composite membrane and its appliance in dye waste Rhodamin-B separation has been done. The purpose of this research was to determine membrane composition which have the best mechanical propertie, surface morphology, and poresite membrane. To meansure mechanical strength have done straight and strain tested membrane using autograph. Whereas to determine membrane performance, have done flux and rejection test using “dead end” membrane test using variated pressure range 1-4 kg/cm2. To determine morphologi surface and membrane pore has done analyzed using Scanning Electron Microscopy (SEM). The best result with 75%:25% has the best mechanical strenght 36.926 kgf. Its membrane has pore size denser approximately 0.01-0.15 µm, whereas the best flux get in membrane with ratio 50%:50% 21,544 l/m2.hour use pressure 4 kg/cm2. The best result of rejection test is 87.029% result by membrane has ratio 75%:25% use pressure 1 kg/cm2.
