The Decolorization and Phytotoxic Efficiency of Jackfruit Seed on a Textile Dye Novacron Blue

Abstract

Industrial wastewater containing dye can cause severe destruction to the human immune system as well as the nervous system. The purpose of the present study is to optimize the decolorization of a textile dye Novacron blue on the surface of jackfruit seed powder (JSP). Jackfruit seed can be obtained at a low cost and be used without further purification/chemical treatment to adsorb some pollutants on its surface. About 73% of Novacron blue was adsorbed on the surface of JSP after 60 minutes of contact time. Effects of various physico-chemical parameters such as adsorbent dose, initial dye concentration, pH, temperature, and contact time on the adsorption of Novacron blue have been investigated. The adsorption was found to be increased initially with the adsorbent dose and become maximum at 10 g of the adsorbent. The maximum adsorption capacity was 0.732 mg/g. The decolorization efficiency was inversely proportional to the initial concentration of Novacron blue. Basic medium and low temperature are preferred by the adsorbent for the adsorption of Novacron blue on JSP.  Kinetics of adsorption was accomplished with the pseudo-first-order and pseudo-second-order model. Phytotoxic study on Red Amaranth reveals the abolishment of hazardous species from the wastewater.
