The current examine was carried out to grasp the power of functionalized unzipped multi-walled carbon nanotube oxides for methylene blue dye adsorption. Parameters that affect the dye adsorption effectivity corresponding to quantity of adsorbent, adsorption time, stirring velocity and pH of resolution have been optimized. Dye elimination effectivity of 99.8% and most adsorption capability of 420.14 mg/g have been obtained with the optimum circumstances corresponding to 20 mg of adsorbent, pH 7–9 of the answer and stirring velocity of 400 rpm for 15 min. The outcomes from the kinetic examine revealed that the adsorption of methylene blue dye on the ready nano-adsorbent adopted pseudo-second-order kinetic mannequin. Langmuir isotherm was discovered to be finest match for the adsorption of methylene blue dye with functionalized nano-particles. Additionally, the reusability examine confirmed a dye elimination effectivity of 94% even after six cycles of adsorption–desorption. The nano-particles produced within the current examine are discovered to be an efficient adsorbent for the elimination of methylene blue dye from waste water.
