Daftar Isi:
- Synthesis and characterization of Fe3O4/chitosan/clay Bangka has been carried out. Synthesis of composite was done with variations the composition of clay (0; 25; 50; 100 %) at the composition of Fe3O4 95 mg of Fe3O4 and 1 gr of chitosan. Characterization of composite Fe3O4/chitosan/clay have been analysed with XRD, FTIR, porosity test, the degree of development, and adsorption efficiency test for Cu2+ ion. The results of the analysed with XRD show the difractogram of clay and Fe3O4 at 2θ= 8,92o, 29,57o, and 45,61o (clay); 26,90o, and 35,64o (Fe3O4). Results of the analysed with ftir show the spectrum of the chitosan, clay, and Fe3O4 at 3825, 3689, 2103, 1425 cm-1 (chitosan), 1028, 884,41 cm-1 (clay), 791,11 cm-1 (chitosan) and 696,95 cm-1 (Fe3O4). The results of porosity test and the degree of development showed the high point are 1,547 and 754,63% without composition of clay. The adsorption test for Cu2+ ion show percentage of adsorption efficiency is 72,41% at composite of Fe3O4/chitosan with the clay added 1 gr.
- Sintesis dan karakterisasi komposit Fe3O4/kitosan/kaolin Bangka telah dilakukan. Sintesis komposit dilakukan dengan memvariasikan komposisi kaolin (0; 0,25; 0,5; dan 1 gr). Pada komposisi Fe3O4 95 mg dan kitosan 1 gr. Karakterisasi komposit Fe3O4/kitosan/kaolin dilakukan dengan analisis XRD, FTIR/, uji porositas, derajat pengembangan, dan uji adsorpsi pada ion Cu2+. Hasil analisis XRD menunjukkan adanya puncak difraksi kaolin dan Fe3O4 pada 2θ= 8,92o, 29,57o, dan 45,61o (kaolin) serta 35,64o, dan 45,61o (Fe3O4). Hasil analisis FTIR menunjukkan adanya pita serapan yang khas dari kitosan, kaolin, dan Fe3O4 pada hasil analisis FTIR menunjukkan ada pita serapan pada daerah 3825, 3689, 2103, dan 1425 cm-1 (kitosan), 1028, dan 884,41 cm-1 (kaolin), 791,11 cm-1 (kitosan), dan 696,95 cm-1 (Fe3O4). Nilai porositas tertinggi yaitu 1,547% tanpa penambahan kaolin, derajat pengembangan tertinggi yaitu 754,63 % juga tanpa penambahan kaolin. Uji adsorpsi terhadap ion Cu2+ menunjukkan nilai efisiensi adsorpsi sebesar 72,41% pada penambahan kaolin 1 gr.
