In this paper, we have applied a new Chebyshev wavelet based coupled method to film-pore diffusion model. We have used the film-pore diffusion model, satisfactorily describe kinetics of methylene blue adsorption onto the three low-cost adsorbents, Gauva, teak and gulmohar plant leaf powders. We first discretize the nonlinear PDE and then utilized the Chebyshev wavelets on the obtained discretize nonlinear differential, equation to get the solution at each approximation of Picard method. The proposed wavelet based results are compared with the results, obtained by method of lines (MOL) and experimental results. Satisfactory agreement with the experimental and MOL results is observed
