Abstract: Coconut tree flowers waste was investigated as a low-cost and effective adsorbent for the adsorption of Reactive Orange 16 from aqueous solution. Physico - Chemical characteristics of the adsorbents were studied as per the standard testing methods. Effect of various parameters such as agitation time, adsorbent dose and concentration, pH, temperature have been investigated in the present study. The adsorption of dyes have been best described by pseudo second order kinetic model and Langmuir adsorption Isotherms. The negative values of the ∆Gº and positive value of the ∆Hº indicate that the sorption process is spontaneous and endothermic in nature. The positive value of ∆Sº shows the increasing randomness during adsorption process. Desorptive studies reveals that no satisfactory desorption taking place indicating chemisorptive nature of adsorption.
