MULTILAYER POROUS COMPOSITE FROM WASTE GLASS FOR WATER FILTRATION

Multilayer porous composite have been produced through the heating process at temperature T= 700 degrees C for 2.5 h. Single layered porous composite was made with a varied mass percentage of from PEG polymer 1% to 10%. Double-layered porous composite were made by the arrangement of porosity (4: 3)%, (4: 2)% and (3: 2)%, while the three-layers porous composite have an arrangement (4: 3: 2)%. Performance of multilayer porous composite for water filtration with pollutants of methylene blue 100 ppm was estimated from the absorbance spectrum. Rejection of methylene blue pollutants from single layered porous composite increases when the fraction of PEG polymer tend to be smaller in the matrix. Meanwhile, the double layered porous composite has a degradation of methylene blue pollutants are better than one layer. Triple layered porous composite have good performance for the water filtration where all the pollutants of methylene blue be able to be filtered. (C) 2015 Jurusan Fisika FMIPA UNNES Semarang
