Asto, EkoSusanto (2014) Pengaruh pH, Lama Kontak, dan Konsentrasi pada Adsorpsi Ion Logam Cu2+ Menggunakan Kitin Terikat Silang Glutaraldehid. Sarjana thesis, Universitas Brawijaya.
Abstract
Telah dilakukan penelitian pengaruh pH, lama kontak, dan konsentrasi pada adsorpsi ion logam Cu2+ menggunakan kitin terikat silang glutaraldehid. Penelitian ini diawali dengan pembuatan kitin terikat silang glutaraldehid. Hasil pembuatan kitin terikat silang glutaraldehid diidentifikasi gugus fungsionalnya dengan FT-IR serta dihitung derajat deasetilasinya, dan dilakukan SEM-EDX untuk mengetahui morfologi dari kitin terikat silang glutaraldehid. Penentuan kondisi dilakukan melalui variasi pH 2, 3, 4, 5, dan 6, dan lama kontak 20, 40, 60, 80, 100, dan 120 menit, sedangkan kapasitas adsorpsi dilakukan dengan variasi konsentrasi 150, 175, 200, 225, dan 250 ion logam Cu2+. Nilai derajat deasetilasi kitin terikat silang glutaraldehid sebesar 11,85%, lebih kecil dari derajat deasetilasi kitin 22,46%. Hasil identifikasi dengan SEM-EDX menunjukkan bahwa morfologi kitin terikat silang glutaraldehid lebih tertata rapi dengan prosentase C sebesar 50%, sedangkan kitin sebesar 33%. Spektra IR kitin menunjukkan adanya serapan gugus C-N pada panjang gelombang 1317,79 cm-1. Pada kitin terikat silang glutaraldehid serapan gugus C-N muncul pada panjang gelombang 1419,51 cm-1. Kondisi optimum adsorpsi terjadi pada pH 4 dengan prosentase adsorpsi 66,24%, dan lama kontak terjadi pada menit ke-100 dengan prosentase adsorpsi 90,19%. Kapasitas adsorpsi kitin terikat silang glutaraldehid terhadap ion logam Cu2+ sebesar 45,10 mg/g.
English Abstract
Research about the influence of pH, adsorption time, and concentration toward Cu2+ metal ion adsorption using glutaraldehyde crosslinked chitin has been performed. This research begins with the manufacture of glutaraldehyde crosslinked chitin. Identification of the results of glutaraldehyde crosslinked chitin’s functional groups was done using FT-IR and its degree of deacetylation was also calculated, and also SEM-EDX was performed to determine the morphology of glutaraldehyde crosslinked chitin. Determination of the condition was done with pH of 2, 3, 4, 5, and 6, and the adsorption times of 20, 40, 60, 80, 100, and 120 minutes, mean while the adsorption capacity was performed by variation of the Cu2+ metal ion concentration of 150, 175, 200, 225, and 250 ppm. Degree of deacetylation of glutaraldehyde crosslinked chitin was 11.85%, smaller than degree of deacetylation of chitin 22.46%. The results of identification with SEM-EDX showed that the morphology of glutaraldehyde crosslinked chitin more orderly with a percentage of 50% C, whereas chitin by 33%. IR spectra of chitin showed that the presence of the C-N group absorption at a wavelength of 1317.79 cm-1. In glutaraldehyde crosslinked chitin C-N group absorption appears at a wavelength of 1419.51 cm-1. Optimum condition of the adsorption was occured at pH of 4 with adsorption percentage of 66.24%, and the adsorption time was occured at 100 minutes with adsorption percentage of 90.19%. Adsorption capacity of the glutaraldehyde crosslinked chitin toward Cu2+ metal ion was 45.10 mg/g.
