Abstract

Sintesis nanopartikel besi (NP Fe) menggunakan metode elektrolisis telah dilakukan. Prosedur sintesis NP Fe dilakukan dengan menggunakan logam besi sebagai anoda dan katoda dalam larutan 0,01 M Na2SO4. Larutan Na2SO4 berfungsi sebagai larutan elektrolit. Proses elektrolisis dilakukan pada variasi tegangan sebesar 10-50 V. Pengaruh penambahan ekstrak bunga telang (Clitoria ternatea) sebagai agen capping dipelajari pada proses sintesis NP Fe. Ekstrak bunga telang diperoleh dengan cara maserasi dalam air. Penambahan ekstrak bunga telang dilakukan sebelum (NP Fe-V1) dan setelah (NP Fe-V2) proses elektrolisis. NP Fe juga disintesis tanpa penambahan ekstrak bunga telang sebagai perbandingan. NP Fe hasil sintesis dikarakterisasi menggunakan metode spektrofotometri ultraviolet-visible (UV-Vis), X-ray diffraction (XRD), Field emission scanning electron microscopy-Energi Dispersive X-Ray (FESEM/EDX), dan particle size analyzers (PSA). Hasil analisis UV-Vis menunjukkan puncak serapan NP Fe-V1 pada 300-330 nm dan NP Fe-V2 pada 330-360 nm. Hasil analisis PSA menghasilkan ukuran rata-rata partikel NP Fe-V1 sebesar 167,2 nm dan NP Fe-V2 sebesar 352,8 nm. Hasil analisis XRD mengindikasikan NP Fe-V1 adalah material amorf dan NP Fe-V2 merupakan kristalin Fe3O4 yang telah diverifikasi menggunakan JCPDS 19-0629. Analisis morfologi menggunakan FESEM menunjukan NP Fe-V1 memiliki ukuran partikel rata-rata sebesar 39,63 nm dan sebesar 60,16 nm untuk NP Fe-V2. Analisis EDX menunjukkan kandungan Fe dan O pada NP Fe-V1 dan NP Fe-V2. Hasil karakterisasi menunjukkan pembentukan nanopartikel besi oksida. ==================================================================================================================================
The synthesis of iron nanoparticles (FeNPs) using the electrolysis methods has been carried out. The synthesis was conducted using iron metal as both anode and cathode submerged in 0,01 M Na2SO4 solution. The Na2SO4 solution were used as electrolyte. The electrolysis process was carried out at various voltages of 10-50 V. The influence of adding butterfly pea flower (Clitoria ternatea) extract as a capping agent was obtained by maceration in water. The addition of the butterfly extract was done before (NP Fe-V1) and after (NP Fe-V2) the elctrolysis process. Fe NPs were also synthesized without butterfly pea flower extract addition. The Synthesized FeNPs were characterized using ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy-Energy Dispersive X Ray (FESEM/EDX), and particle size analyzers (PSA). UV-Vis analysis showed an absorption peak for NP Fe-V1 at 300-330 nm and for Fe NP-V2 at 330-360 nm. PSA analysis results indicated the average particle size of NP Fe-V1 to be 167.2 nm and NP Fe-V2 to be 352.8 nm. XRD analysis results indicated that NP Fe-V1 is amorphous, and NP Fe-V2 is Fe3O4 that has been verified by JCPDS 19-0629. Morphological analysis using FESEM showed that NP Fe V1 had an average particle size of 39.63 nm and 60.16 nm for NP Fe-V2. EDX analysis showed the presence of Fe and O in both Fe NP-V1 and Fe NP-V2. The characterization results indicated the formation of iron oxide nanoparticles.
