Abstract

Moringa seed peel powder was used to remove methylene blue dye from the aqueous solution. The surface of the Moringa seed peel powder was characterized using (FT-IR) infrared spectroscopy, (BET) surface specification, and (SEM) scanning electron microscopy. The influencing factors were studied. On adsorption, which is the amount of adsorbent, contact time, initial concentration of the dye, temperature, and acid pH to predict the optimal conditions under which the adsorption process takes place. Adsorption equilibrium and adsorption rate data were evaluated using different isotherm and kinetic models. The isotherm results showed that the Langmuir model gave better results for the studied equilibrium data. The adsorption kinetic data better follow the pseudo-second order model. Thermodynamic variables were also evaluated and the calculated parameters indicated that the adsorption process was spontaneous and exothermic in nature.
