Abstract

Abstract

Palm fiber has the potential to be synthesized into nanofiber because it contains high enough cellulose, about 40-60%. The synthesis of nanofibers was carried out by chemo-mechanical methods. Chemical processes included delignification by alkali, acid hydrolysis, and bleaching. Meanwhile, the mechanical process consisted of grinding. Modifications were also made to the formed nanofibers, namely nano oxide coating. This study aimed to determine (1) the synthesis of nanofiber materials with palm fiber waste as adsorbent, (2) the crystallinity of the nanofiber structure, (3) the adsorption capacity of nanofiber adsorbents against congo red and methylene blue. FTIR characterization showed that the nanofiber material had been successfully synthesized, marked by specific peaks indicating the cellulose-forming functional group, namely -OH group at the peak of 3415.12 cm-1, -CH group at the peak of 2897.21 cm-1, -CO group at the peak of 1635.71 cm-1, and -CH2 at peak 1431.24 cm-1. The crystallinity of the nanofibers reached 74.933% based on XRD results. Besides, this nanofiber had high adsorption power for cationic dyes (methylene blue) and lower adsorption power for anionic dyes (congo red). The maximum adsorption capacity (mg/g) of Nf HCl, Nf HCl + Fe 3%, Nf HCl + Fe 5% with contact temperatures of 30oC, 40oC, 50oC to methylene blue was 9.973; 9.959; 9.539; 9.924; 9.904; 9.698; 9.952; 9.931; 9.636; respectively. Meanwhile, the maximum adsorption capacity (mg/g) of Nf HCl, Nf HCl + Fe 3%, Nf HCl + Fe 5% with temperatures of 30oC, 40oC, 50oC against congo red respectively was 8.579; 9.421; 9.711; 8.184; 8.921; 9; 8.947; 8.342; 7.263. This results will be beneficial as a strategy to utilize the palm fiber waste for dyes removal from the aquatic ecosystem.
