description: Nanofiber is a material composed of nanometer-scale fibers with carbon or polymer base materials.The easiest and most economical method of nanofiber synthesis is electrospinning. The most economical method of nanofibers synthesis is electrospinning.Nanofiber has the high potential for CO 2 adsorption because it has high gas transport resistance and high kinetic (Wang and Li, 2014). Nanofiber has a high potential for CO2 adsorption because it has high gas transport resistance and high kinetic [1].Application of synthetic polymer-based nanofiber for CO 2 adsorption has been carried out by several researchers including PVDF nanofiber (Hong et al., 2014), phenolic resin nanofiber (Nan et al., 2015), and PDMS/PVDF nanofiber (Lin et al., 2016). Research on the synthesis of Alginate/Polyethylene oxide/Triton X-100 nanofibers (Alg/PEO/TX NFS) by electrospinning method for CO 2 adsorption was carried out.Research on synthesis of Alginate/Polyethylene oxide/Triton X-100 nanofibers (Alg/PEO/TX NFs) by electrospinning for CO2 adsorption was carried out.This study aims to determine the composition of Alg/PEO that can produce fibers without beads; The purpose of this research werethe effect of adding PEO and TX to the electrospinnability of the solution ; to study the effect of adding PEO and TX to the electrospinnability of the solution, andthe effect of flow rate and contact time on adsorption capacity; the effect of the gas flow rate and contact time on adsorption capacity and the study of CO 2 adsorption isotherm by Alg/PEO/TX NFS.of Alg/PEO/TX NFs.Polymer solutions were characterized by conductivity meters and tensiometers, while nanofibers were analyzed using optical microscopy, SEM, and FTIR. Polymer solutions were characterized by the conductivity meter and tensiometer, while the nanofibers were analyzed using optical microscopy, SEM, and FTIR.The study of CO 2 adsorption in nanofiber includes the effect of flow rate and CO 2 contact time on nanofiber, then studied adsorption isotherm. The study of CO2 contact time includes the effect of flow rate and CO2 contact time on nanofiber. The results showed that Alg/PEO/TX NFS without beads were successfully synthesized from a solution of Alg/PEO with a volume ratio of 1:2 and an addition of 0.5% (v/v) TX.The results showed that Alg/PEO/TX NFs were successfully synthesized with a volume ratio 1/2 of Alg/PEO blends solutions and a small addition of 0.5% (v/v) TX.The bead s without nanofiber produced were 201,567 ± 48 nm in diameter and have a surface area of 34,963 m 2 g -1 . The beads-free nanofibers produced was 201 ± 48 nm in diameter and with a surface area of 34,963 m2.g-1.The optimum adsorption capacity was obtained at the rate of 10 mL minute -1 with a contact time of 25 minutes was 12,398 mmol g -1 . The optimum adsorption capacity was 12,398 mmol.g-1, which wasobtained at the flow rate of 10 mL.minute-1 and a contact time of 25 minutes.
