    Abstract

    Microcapsules of chitosan gel beads crosslinked with Ethylene Glycol Diglycidyl Ether (PSF-EGDE-CTS) were prepared to improve adsorption capacity and mechanical stability of chitosan at acidic condition. These microcapsules were prepared through three step i.e. the formation of gel beads (CTS), crosslinked CTS with EGDE (EGDE-CTS) and microencapsulation of EGDE-CTS with Polysulfone (PSF-EGDE-CTS). Product characterizations were carried out using FTIR and SEM. The adsorptions were carried out by variation of pH and contact time in order to determine the optimum condition of adsorption. The yield of Microcapsules PSF-EGDE-CTS was 94,79 wt %. The optimum condition of Procion Red MX 8B dye adsorption by PSF-EGDE-CTS is at pH 5 and 24 hours of contact time. The adsorption capacity of PSF-EGDE-CTS is 40,69 mg/g. Keywords : adsorption, chitosan, crosslink, microcapsules, Procion Red MX 8B. Mikrokapsul kitosan gel tersambung silang etilen glikol diglisidil eter (PSF-EGDE-CTS) telah dibuat untuk meningkatkan kemampuan adsorpsi dan stabilitas kitosan dalam kondisi asam. Mikrokapsul PSF-EGDE-CTS dibuat melalui tiga tahap yaitu pembentukan gel (CTS), proses sambung silang dengan EGDE (EGDE-CTS) dan mikroenkapsulasi dengan PSF (PSF-EGDE-CTS). Karakterisasi hasil sintesis dilakukan dengan spektroskopi FTIR dan SEM. Selanjutnya PSF-EGDE-CTS digunakan untuk uji adsorpsi limbah zat warna Procion Red MX 8B. Adsorpsi zat warna Procion Red MX 8B oleh kitosan termodifikasi dilakukan dengan variasi pH dan waktu kontak untuk mencari kondisi optimum adsorpsi. Mikrokapsul PSF-EGDE-CTS yang diperoleh adalah 94,79% (b/b). Kondisi optimum adsorpsi zat warna Procion Red MX 8B oleh PSF-EGDE-CTS terjadi pada pH 5 dan waktu kontak 24 jam. Daya serap PSF-EGDE-CTS pada uji adsorpsi limbah zat warna Procion Red MX 8B adalah sebesar 40,69 mg/g. Kata kunci : adsorpsi, kitosan, mikrokapsul, Procion Red MX 8B.
