Abstract

Penelitian bertujuan untuk mengetahui pengaruh penambahan aktivator H2SO4 5 M terhadap struktur arang dan daya adsorpsi logam Fe pada kondisi optimum. Arang aktif sebelum dan setelah diaktivasi dianalisis dengan uji kualitas karbon aktif berdasarkan standar SNI 06-3730-1995, XRD dan FTIR. Hasil penelitian menunjukkan hasil uji karbon aktif yang teraktivasi H2SO4 5 M pada analisis kadar air sebesar 9%, kadar abu 3%, kadar volatile matter 12,15% dan kadar karbon murni 84,85% sedangkan hasil uji karbon aktif tanpa aktivasi H2SO4 5 M pada analisis kadar air sebesar 7%, kadar abu 12%, kadar volatile matter 22,08% dan kadar karbon murni 65,92%. Pada hasil analisis persen kadar Fe yang teradsorpsi pada kondisi optimum, untuk arang aktif yang teraktivasi H2SO4 5 M pada kondisi optimum konsentrasi larutan Fe 10 ppm, pH 4, massa 1,5 gram dan waktu kontak 60 menit daya adsorpsi arang aktif sebesar 76,35%, sedangkan untuk arang aktif tanpa aktivasi H2SO4 5 M pada kondisi optimum konsentrasi larutan Fe 10 ppm, pH 4, massa 0,5 gram dan waktu kontak 60 menit daya adsorpsi arang aktif sebesar 51,09%. Pada hasil analisis XRD terhadap arang aktif yang teraktivasi H2SO4 5 M menunjukkan karbon berstruktur mendekati amorf, sedangkan arang aktif tanpa aktivasi menunjukkan karbon berstruktur kristal. Kemudian karakterisasi dengan FTIR menunjukkan munculnya spektra pada bilangan gelombang 2335,00 cm-1 dan 2360,23 cm-1 merupakan vibrasi regangan gugus -C=N, munculnya gugus fungsi C-O pada bilangan gelombang 1300-1200 serta vibrasi logam (mineral pada bilangan gelombang 624,11 cm-1.
