Pada studi ini, saya menggunakan metode fotokatalitik untuk mendegradasi limbah cat pewarna organik dalam limbah air menggunakan MgFe2O4 dan MgFe2O4-nanographene (MgFe2O4/NGP) nanopartikel. MgFe2O4 dan MgFe2O4/NGP (mengandung persentase NGP yang bervariasi) disintesis melalui metode hidrotermal. Kedua bahan ini digunakan sebagai katalis dalam proses fotokatalitik mendegradasi limbah organic Methylene-Blue dalam solusi cair, dibawah radiasi cahaya merah. Karakteristik dari sample (MgFe2O4 & MgFe2O4/NGP) dilakukan menggunakan X-ray Diffraction, Raman Spectroscopy, UVVIS Spectroscopy, XRF, TGA, BJH, XPS, TEM, HRTEM, SAED, EDX dan BET. Hasil dari penelitian ini menunjukkan bahwa MgFe2O4/NGP mempunyai kemampuan fotokatalitik yang lebih baik dibandingkan dengan MgFe2O4. Efek dari konsentrasi NGP (wt%) untuk mendegradasi MB didiskusikan. Spesies aktif dalam proses fotokatalitik juga dipelajari melalui scavenger test.
In the current study, we use the photodegradation method for the removal of organic dye molecule in wastewater using MgFe2O4 and MgFe2O4-nanographene platelets (MgFe2O4/NGP) nanoparticles. MgFe2O4 and MgFe2O4/NGP (containing various amounts of NGP) were synthesized using the hydrothermal method. Both of them used as a catalyst for photocatalytic degradation of methylene blue (MB), i.e. our organic dye in aqueous solution under red light irradiation. Characteristics of our samples (MgFe2O4 & MgFe2O4/NGP) were characterized using X-ray diffraction, Raman Spectroscopy, UVVIS Spectroscopy, XRF, TGA, BJH, XPS, TEM, HRTEM, SAED, EDX, and BET. The result of our work showed that MgFe2O4/NGP mostly have a better photocatalytic performance compared to pure MgFe2O4. The effect of NGP concentration (wt%) on the photocatalytic degradation of MB was discussed. Active species who'd take effect on the photocatalytic process was also studied by the scavenger test. |
