Methyl orange's production and use as a pH indicator and as a dye for textiles may result in its release to the environment through various waste streams. Heat the solution to boiling. Adsorption kinetic data were then fitted using pseudo first-order, pseudo second-order, and Eelovich models, with the results showing that the pseudo second-order model had the best fit for both dyes amongst all the models used in both single and binary-dye systems(R2 > 0.996). Methyl orange shows red colour in acidic medium and yellow colour in basic medium (1). Blue, orange, yellow, and red are just some of the colors you may see when testing a solution using an acid-base indicator.
