Adsorption Rate of Dyes onto Carbonaceous Materials Produced from Waste Fibers

Abstract

Waste fibers are produced by textile industry and colored wastewater is released, the people hope to development the useful reused methods of it. And the release of colored wastewater induced aesthetically unpleasant, produced the carcinogen from chlorination. In this study, we produced the carbonaceous materials produced from waste fibers, developed the amount adsorbed and the adsorption rate of dyes. As a results, the specific surface area of waste fibers is increasing with increasing the carbonized temperatures. Amount adsorbed of each dyes onto carbonaceous materials produced from waste fibers at 1000oC is highest. In waste fibers, amount adsorbed of each dyes onto 2 h heating-2 h maintaining carbonaceous materials produced from waste fibers is increasing colored wool < untreated wool < colored wool-polyester < polyester, it showed the waste fiber from polyester is more suitable for adsorption than that of wool. Carbonaceous materials produced from waste fibers at 1000oC could treat to adsorbed the Methylene blue and Orange II in 20 min from the adsorption beginning. The carbonaceous materials produced from waste fiber would be utilized for adsorbates to remove dyes.
