Abstract
The development of the textile industry is one of the main sources of dye waste I the environment, which means that the discharged wastewater is still concentrated and smelly when observed directly on the ground, thus contributing to water pollution. The aim of this study is to determine the relationship between the concentration of methylene blue dye and the adsorption time and to determine the adsorption isotherm. For the synhesis of graphene oxide, the hummer’s method was used where graphite wes recombined with H2SO4 sulfuric acid and the adsorbed solution was measured using UV-Vis spectrophotometer. Graphene oxide acted as an adsorbent by adsorbing methylene blue and the result showed that he optimum time and concetration was acheieved at a 30 ppm and 25 minutes. The adsorption mechanism aligns with the Langmuir model, demonstrated by an R2 value of 0.92522, a Qm value of 99.1 mg.g -1 , and a K value of 0.325.
