Abstract
In this research, the Date Seed (DS) was investigated to remove the anionic dyes from textile effluent as a biosorbent. Direct Blue 78 (DB78) and Acid yellow 36 (AY36) were used as anionic dyes. The surface characteristics of DS were investigated using Fourier Transform Infra-Red and Scanning electron microscope. The influence of process variables such as adsorbent dosage, initial dye concentration and pH were studied. The isotherm and kinetic of dye adsorption onto DS were studied. The results indicated that the data for adsorption of DB78 and AY36 onto DS fitted well with Langmuir isotherms. The rates of sorption were found to conform to pseudo-second order kinetic with good correlation. Results indicated that DS could be used as a biosorbent to remove the anionic direct and acid dyes from contaminated watercourses.
