WebbIsotherm models of Langmuir, Freundlich, Langmuir–Freundlich (LF), Dubinin–Radushkevich (DR model) and Temkin were examined on the aqueous MG and CR dye solutions. Selective adsorption of both dyes was also studied with all composites and it was found to be different from the one component aqueous dye solution adsorption.
