Due to a large-scale production and extensive\u00a0application of azo dyes, it can cause considerable amount of polluted wastewater and can generate serious\u00a0health-risk factors. Chitosan, a low cost adsorbent has been widely used to treat azo dye. Recent studies\u00a0had discovered heterogeneous photocatalysis using semiconductors such as zinc oxide is quite applicable\u00a0because of its ability to decolorize dye-containing wastewater more effectively. The purpose of this research\u00a0is to hybridize the low-cost adsorbent chitosan and semiconductor zinc oxide to produce an adsorbent which\u00a0has high efficiency for removing azo dye. The parameters that were used in this study are pH values (pH\u00a05.0 to 9.0), temperature (25 to 60\u25e6C) and the initial dye concentration (0.10 to 1.00 mg\/L). The results\u00a0obtained showed that hybrid chitosan and zinc oxide adsorbent had successfully decolorized ethyl orange<br \/>\ndye in water. The optimum conditions for the highest removal of ethyl orange (85%) were achieved at\u00a0following conditions; temperature of 60\u00b0C, using adsorbent containing 1 g of chitosan and 2.0wt % of zinc\u00a0oxide, 1.0 mg\/L of dye concentration, at pH 7 and 2 hours of mixing time with 130 rpm of mixing rate. In\u00a0this study, the adsorption process was found to fit the Freundlich isotherm than of the Langmuir isotherm.<\/p>\n<p>Click this link for view full paper:\u00a0<a href=\"https:\/\/people.utm.my\/mazurajusoh\/wp-content\/blogs.dir\/878\/files\/2014\/12\/1665-6775-1-PB.pdf\">1665-6775-1-PB<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract Ethyl Orange is a type of water-soluble azo dye, which is widely used in the textile, printing, paper\u00a0manufacturing, pharmaceutical and food industries.
