The current research was carried out to know the power of functionalized unzipped multi-walled carbon nanotube oxides for methylene blue dye adsorption. Parameters that affect the dye adsorption effectivity similar to quantity of adsorbent, adsorption time, stirring pace and pH of answer had been optimized. Dye elimination effectivity of 99.8% and most adsorption capability of 420.14 mg/g had been obtained with the optimum circumstances similar to 20 mg of adsorbent, pH 7–9 of the answer and stirring pace of 400 rpm for 15 min. The outcomes from the kinetic research 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 greatest match for the adsorption of methylene blue dye with functionalized nano-particles. Additionally, the reusability research confirmed a dye elimination effectivity of 94% even after six cycles of adsorption–desorption. The nano-particles produced within the current research are discovered to be an efficient adsorbent for the elimination of methylene blue dye from waste water.
