Meilia, Demara (2018) Sintesis Komposit ZnFe2O4/Karbon Aktif dan Aplikasinya untuk Adsorpsi Parasetamol. Sarjana thesis, Universitas Brawijaya.
Abstract
Arang kayu yang berpori merupakan biochar yang dibuat dari hasil pirolisis. Biochar dari arang kayu dapat diaplikasikan sebagai adsorben. Dalam penelitian ini, komposit ZnFe2O4/Karbon Aktif disintesis untuk dapat mempelajari pengaruh perbandingan mol Fe(III):Zn(II) terhadap sifat kimia dan adsorpsi parasetamol. Penelitian ini dilakukan dengan beberapa tahap, yaitu aktivasi karbon aktif dengan KOH (suhu kamar, 2 jam), oksidasi karbon aktif dengan H2SO4 6M (80oC, 3 jam), dan pembentukan komposit Zn-Fe-LDH/Karbon Aktif melalui metode kopresipitasi dengan perbandingan mol Fe(III):Zn(II) (1:2, 1:3, dan 1:4), kalsinasi komposit menjadi ZnFe2O4/Karbon Aktif (950OC, 5 menit). Karakterisasi komposit dilakukan dengan menggunakan XRD dan spektrofotometri FTIR. Uji adsorpsi dilakukan dengan parasetamol 100 mg/L (24 jam, 200 rpm). Kapasitas adsorpsi dilakukan dengan konsentrasi parasetamol 50-90 mg/L. Konsentrasi parasetamol ditentukan dengan menggunakan spektrofotometri UV-Vis pada 243 nm. Hasil karakterisasi biochar dengan spektrometri FTIR menunjukan adanya gugus Fe-O dan Zn-O yang semakin meningkat dengan kenaikan perbandingan mol Fe(III):Zn(II). Uji adsorpsi menunjukkan adanya peningkatan adsorpsi dengan perbandingan mol Fe(III):Zn(II) dari 1:2 sampai 1:4. Berdasarkan model Langmuir, kapasitas adsorpsi dicapai sebesar 4,3783 mg/g.
English Abstract
Porous wood charcoal is a biochar made from pyrolysis. Biochar from charcoal can be applied as an adsorbent. In this study, the composite of ZnFe2O4/Activated Carbon was synthesized to study the effect of mole ratio of Fe(III):Zn(II) on chemical properties and paracetamol adsorption. This research was conducted with several stages, namely activation of activated carbon with KOH (room temperature, 2 hours), activated carbon oxidation with H2SO4 6M (80oC, 3 hours), and the formation of composite of Zn-Fe-LDH/ Activated Carbon through coprecipitation method with a mole ratio of Fe(III):Zn(II) (1:2, 1:3, and 1:4), composite calcination becomes ZnFe2O4/Activated Carbon (950OC, 5 minutes). The composite characterization was performed using XRD and FTIR spectrophotometry. The adsorption test was performed with paracetamol 100 mg/L (24 hours, 200 rpm). The adsorption capacity was performed with concentrations of 50-90 mg/L paracetamol. The concentration of paracetamol was determined using UV-Vis spectrophotometry at 243 nm. The result of biochar characterization with FTIR spectrometry showed that Fe-O and Zn-O groups were increasing with the increase of mole ratio Fe(III):Zn(II). The adsorption test showed an increase in adsorption by the mole ratio of Fe(III):Zn(II) from 1:2 to 1:4. Based on the Langmuir model, the adsorption capacity was achieved at 4,3783 mg/g.
