Studies of the Dimensionless Mass-transfer Coefficient During the Adsorption of Basic and Acid Dyes on to Bagasse Pith

Abstract

The influence of agitation, particle diameter and mass of adsorbent on the external mass-transfer coefficient is discussed. The computed values correlate with the dimensionless function Sh/Sc^1/3. It has been found that Sh/Sc^1/3 varies linearly with the variables studied and may be correlated with system variables via the equation Sh/Sc^1/3 = A(variable)^B.
