We study the influence of the interaction of curvature and a weak wall absorption parameter on the dispersion process using Taylor analysis. A perturbation series solution has been obtained to find the values of the effective dispersion coefficient. The constraints imposed by the perturbation techniques have been removed using a numerical scheme based on spectral method. Results are found to be applicable for a time at which the Taylor dispersion model holds. It has been observed that in the interphase transport of reactive contaminants the effective dispersion coefficient is significantly different from that of Taylor due to the wall absorption parameter. The results corresponding to the straight tube are verified with the published results.
