Abstract In this work adsorption and kinetic modelling of the uptake of water from ethanol – water mixtures using starchy adsorbents was undertaken. These include modified cassava starch (MSAD), cassava starch (CSAD), cassava pellet (CPAD), and cassava shred (ABAD). The kinetic data were obtained in a finite volume bath cell circulation at room temperature (28 o C). Five kinetic models including First order, Pseudo – first order, Pseudo – second order, Pore diffusion and Elovich equations were tested for uptake of water by these starchy adsorbents from ethanol – water systems. The results revealed that the adsorbents types and molecular diffusion of water molecules on the surface of the adsorbents play an important role in the uptake of water by these adsorbents. The performance of the adsorbents for the net uptake of water was found to be in the order; MSAD> CSAD> CPAD>>ABAD.
