| dc.description.abstract | Ibuprofen is a nonsteroidal anti-inflammatory drug that is considered one of the most dangerous drugs in pollution of various liquid waste that can cause digestive disorders, kidney failure, nausea and headache in humans. The fotokatalis-based semiconductor Process such as reducing agents that are able to degrade organic pollutants (ibuprofen) in pharmaceutical waste. In this study Multiferoik BiFeO3-, BiFeO3-doping Ghd (Gadolinium) and Ce (Cherries) have been successfully synthesized using the sole method and obtained the characterization of pure BiFeO3, BiFeO3 dopan Gd and Ce at different concentrations using FTIR, XRD, LEM-VSM, and XRF samples. The sole method of one of the synthesis's techniques of a fairly simple and easy. In the process there is a transition from the "sole" liquid to be solid "gel". At the sole process, the crystalline was further analyzed using XRD to determine the crystal phase from BiFeO3, BiFeO3/Gd and BiFeO3/Ce of the synthesis obtained by crystal with trigonal crystal structure (hexagonal axes) with R3c group space. As well as analyzed using FTIR that can prove the success of multiferoik BiFeO3 synthesis with the Bi-O/functional group (in the range of 526-580 cm-1) and Fe-O (in the range of 400-600 cm-1). Obtained by a crystal with fast) (properties with an average crystal size) (and a disordered lump-shaped morphologically. The heavy composite of the elements make up by an average Bi (47-57)%, Fe (23-37)%, O (10-25)%, Gd (3-9)%, Ce (4-7)%. Multiferoik BiFeO3, BiFeO3/Gd and BiFeO3/Ce in this study has ferromagnetik properties. Activity tests on ibuprofen acquire relegation for pH 2, 0.1 grams, with 30 minutes, at BiFeO3 Dopan Ce 10% material. Fotodegradasi, ibuprofen with a UV light, producing an activity of (58.55%, 61.86%, and 65.44%) higher than lighting of visible, namely (52.63%, 54.48%, and 57.44%). | en_US |
