Adsorption of methyl orange (MO) using an c montmorillonite has been investigated. Which was used for the first time like an adsorbent for removing anionic dye from aqueous solution, the influences of several parameters such as contact time, adsorbent dose, pH and temperature on the adsorption of methyl orange have been tested. The results showed that nearly 40 min of contact time are found to be sufficient for the adsorption to reach equilibrium. The residual concentration of the dye is determined using UV/Vis Spectrophotometer at wavelength 464 nm. Langmuir and Freundlich isotherm models were used to describe adsorption data. Adsorption kinetics was best described by the pseudo-second order model.
