The research of the present work was to investigate the removal of Malachite Green from aqueous solution by using Cyamopsis Tetragonoloba Stem. Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Cyamopsis Tetragonoloba Stem was studied for its potential use as an adsorbent for removal of Malachite Green. The various factors affecting adsorption, such as initial dye concentration, contact time, adsorbent dose and effect of temperature, were evaluated. The experimental data were fitted into the pseudo-second order kinetic model. The equilibrium of adsorption was modeled by using the Langmuir and Freundlich isotherm models. The objective of the present work suggests the ACTNC may be utilized as a low cost adsorbent for Malachite Green dye removal from aqueous solution.
