synthesis and characterization composite Fe3O4/chitosan/clay Bangka

Abstract

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= 8,92^o, 29,57^o, and 45,61^o (clay); 26,90^o, and 35,64^o (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.
