Modification of cellulose with acetic acid to removal of methylene blue dye

Abstract

The study on cellulose modification with acetic acid to cellulose-acetate has been carried out. Cellulose is extracted from the kepok banana peel (Musa paradisiaca L.). Modified cellulose acetate was characterized by FTIR spectroscopy and SEM-EDS. Cellulose acetate to removal of methylene blue with adsorption parameter include initial concentration (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 mg/L), pH solution (3, 4, 5, 6, 7, and 8) and contact time (15, 30, 45, 60, 75, and 90 minutes). The peak of FTIR cellulose acetate obtained by functional groups -OH, C-H, C=O, and C-O esters. The morphology of cellulose-acetate has a more homogeneous than cellulose. Adsorption of cellulose-acetate on methylene blue optimum at an initial concentration of 90 mg/L, pH of solution 6, and contact time of 30 minutes. The adsorption kinetics corresponds to pseudo-second order and adsorption equilibrium corresponds to Langmuir isotherms with adsorption capacity of 42.107 mg/g.

Tailored higher performance silicone elastomer with nanofibrillated cellulose through acidic treatment

“…[32] In treated NFC-A, element C was reduced to more than 5% comparing to control NFC and increased element O was observed in treated NFC-A, indicating the successful acid treatment. [33] Meanwhile, the treated NFC-S has shown the presence of sulfur element at 3.23% as compared to control NFC.…”

Studi Literatur Pengolahan Warna pada Limbah Cair Industri Tekstil Menggunakan Metode Proses Adsorpsi, Filtrasi, dan Elektrolisis

“…Penanggulangan masalah limbah zat pewarna baik secara fisika maupun kimia telah banyak dilakukan dan dilaporkan seperti adsorpsi, filtrasi dan elektrolisis. Adsorpsi merupakan salah satu metode penyerapan fluida, cairan maupun gas dimana zat terserap (adsorbat) terikat oleh zat penyerap (adsorben) pada permukaannya, metode ini telah dilakukan oleh (Guo et al, 2019), (Eletta et al, 2018), (Abd-Elhamid et al, 2019), (Minisy et al, 2019), (Rana et al, 2019), (Adeyi et al, 2019), (FBA & M, 2016), (Ismail et al, 2019), (Hariani et al, 2019), (Fabbricino & Pontoni, 2016), (Huang et al, 2017), (Yin et al, 2017), (Ma et al, 2019), (Sharma et al, 2019). Filtrasi adalah suatu proses pemisahan dengan menggunakan media penyaringan yang menghasilkan filtrat dan residu (ampas), metode ini telah dilakukan oleh (Long et al, 2017), (Gunasegaran et al, 2020), (Zeng et al, 2017), (Kiswanto et al, 2019), (Komala et al, 2019), (Pratiwi & Gunawan, 2018), (Pramitasari, 2017).…”
