Breakthrough curve in adsorption

WebThe breakthrough time and breakthrough curve shape are important features for measuring the operation and dynamic response of fixed-bed adsorption column. The overall breakthrough curve position along the volume or time axis is based on column capacity with respect to i) inlet adsorbate concentration, ii) solution flow-rate, and iii) … WebApr 13, 2024 · The Clark model anticipates the breakthrough curve’s behavior by studying mass transfer and adsorption equilibrium (Kumari et al. 2024; Han et al. 2009). It assumes that the flow in the column is plug flow type, and the Freundlich isotherm is followed by mass transfer occurring in the column (Patel 2024 ).
