Competitive adsorption of p-hydroxybenzoic acid and phenol on activated carbon : experimental study and modelling. [PDF]
, 2013 The competitive adsorption of phenol and p-hydroxybenzoic acid (4HBA) has been investigated on activated carbon (AC) for a wide range of concentrations under unbuffered conditions. The results show a preferential adsorption of 4HBA which can be explained
