Performance of Porous Composite from Waste Glass on Salt Purification Process

Porous composite from waste glass has been synthesized by hydrothermal method. Synthesize process was focus on varies of PEG concentration 1-10%. Herein, the porous composite has been tested as filter on brackish water in order to increase quality of salt. The initial test of filtration result was carried out by conductivity of the filtrate, while FTIR, AAS, and SEM EDX were used to analyze quality of salt. Conductivity of the filtrate decrease which was confirmed by AAS that Na concentration in the salt decreased as well when it was filtered by the composite with higher PEG concentration. SEM EDX of the salt showed morphology of salt crystal with decreasing of impurities such as Mg, C, O and S after filtration process. FTIR analysis indicated decreasing peaks at IR region which corresponds to the reduce impurities concentration. The ability of porous composite from waste glass in order to remove the impurities shows that it can be used in salt purification process.
