Abstract The choice of desorbent, desorption equilibrium and desorption kinetics for reactive brilliant blue KN-R and reactive brilliant red K-2BP, which was absorbed on inactive Aspergillus fumigatus immobilized by caboxymethyl- cellulose sodium (CMC), was investigated. The desorption abilities for reactive brilliant blue KN-R and reactive brilliant red K-2BP absorbed on inactive Aspergillus fumigatus immobilized by CMC were good by 75% ethanol at pH 12.0. The first-order exponential decay equation could describe well the desorption kinetics for reactive brilliant blue KN-R and reactive brilliant red K-2BP adsorbed on inactive Aspergillus fumigatus immobilized by CMC. Their desorption equilibrium data fitted well with the Freundlich desorption equilibrium model.
