Abstract

• The mean of composite are combination of two or more materials present as separate phases and combined to from desired structures so as to take advantage of certain desirable properties of each component. The constituents can be organic, inorganic or metallic in the form of particles, rods, fibers and plates. In this research work, the matrix material (rayon) was prepared from waste paper (A4 printed paper) by using viscose method. The rayon-ZnO nanocomposite fiber was synthesized from zinc chloride and rayon by using melt compounding technique. The synthesized rayon-ZnO nanocomposite was characterized by using EDXRF, FT-IR, SEM and TG-DTA analysis. Synthesized rayon-ZnO nanocomposite was applied in wastewater treatment process. Coagulation and filtration methods were also used to treat the textile wastewater sample. According to the results, rayon-ZnO nanocomposite has good removal efficiency of organic and inorganic pollutant from wastewater. Furthermore, the efficiency of rayon-ZnO nanocomposite was examined by calculation of percent removal efficiency and water quality index (WQI).
