Abstract

The aim of this study was to investigate how basic adsorption isotherms could be applied to predict removal efficiency or required adsorbent mass under given sets of initial conditions. The intrinsic parameters of the Langmuir and Freundlich adsorption isotherms were experimentally obtained and subsequently utilized to predict removal efficiencies for other sets of initial solute concentrations, solution volumes, and adsorbent masses, or to estimate the adsorbent mass required to remove solute at a desired removal efficiency. This was accomplished by combining the isotherms with mass balance of solutes between liquid solution and solid adsorbent phases.
