ABSTRACT

Application of chrysobalanus icaco shell for the removal of an anionic dyes, tartrazine and sunset yellow from aqueous solution by batch adsorption experiment were investigated. The adsorption capacity of the adsorbent was determined. Effect of pH, adsorbent dose, temperature, contact time and initial concentration were determined. The result showed that the optimum adsorption was attained at pH 1 for tartrazine dye and pH 2 for sunset yellow dye, adsorption equilibrium was attained at 120mins.The adsorption capacity increases with increase in initial concentration of 30mg/L to 150mg/L of tartrazine from 5.97mg/g to 23.40mg/g and sunset yellow from 4.05mg/g to 19.65mg/g. The equilibrium adsorption of tartrazine dye and sunset yellow dye on adsorbent was analyzed by Langmuir (R?) values: 0.874 and 0.527, Freundlich (R?) values: 0.896 and 0.759, Temkin (R?) values: 0.747 and 0.901 and Dubinin (R?) values: 0.660 and 0.984. The results indicate that the Freundlich isotherm (R? = 0.896) provide the best correlation for tartrazine dye and Dubinin isotherm provide the best correlation for Sunset Yellow dye (R? = 0.984). The kinetic model of tartrazine dye and sunset yellow dye on adsorbent was analyzed by Pseudo - first order (R?) values: 0.952 and 0.174, Pseudo-second order (R?) values: 0.997 and 0.955, lntraparticle diffusion (R?) values: 0.924 and 0.164 and Liquid film diffusion (R?) values: 0.952 and 0.174. The results of the kinetic study showed that the adsorption process was better described by the Pseudo-second order model with the coefficient of determination (R?) values of 0.997 and 0.955 indicating chemisorption mechanism.
