Single-solute irreversible adsorption on granular activated carbon

Batch and continuous-flow experiments were carried out to study irreversible adsorption and its effect on adsorption equilibria, using 5 substituted phenols of low molecular weight as single-solute systems. The type and position of functional groups on the phenol molecule affected the degree of irre...

Description
Summary:	Batch and continuous-flow experiments were carried out to study irreversible adsorption and its effect on adsorption equilibria, using 5 substituted phenols of low molecular weight as single-solute systems. The type and position of functional groups on the phenol molecule affected the degree of irreversible adsorption. In addition, irreversibility affected the shape of the adsorption isotherms. Although a continuous-flow isotherm procedure could be used to develop an isotherm that might not be affected by irreversibility, this technique suffered from problems of error propagation which made it unacceptable.
