Uji Kinerja Fotodegradasi Kain Terlapisi Komposit Nanosized Chitosan/TiO2 Terhadap Zat Warna Rhodamine B

Abstract

The coating of nanosized Chitosan/TiO2 composit on cotton fabrics substrate and its performance for dye of Rhodamine B was studied. Nanosized Chitosan/TiO2 composit coated on cotton fabrics was done by dip-coating method through pad-dry-cure technic. Cotton fabric thats was coated by nanosized Chitosan/TiO2 composit was characterized by SEM, XRD, and FTIR. Photodegradation Performance test of cotton fabric coated Nanosized Chitosan/TiO2 composit for dye of Rhodamine B was done under UV ray and sun ray.  It was concluded that was cotton fabric coated nanosized Chitosan/TiO2 can decompose dye of Rhodamine B with UV ray more effective than sun ray.
