Enhancement and analysis of Anthracene degradation by Tween 80 in LMS-HOBt

Abstract This study examines the specific effect of Tween 80 on the conversion of anthracene (ANT) in laccase medium system regarding surfactant chemical changes and mechanism. The conversion rate and degradation products of ANT were investigated in different concentrations of Tween 80 solution. Bet...

The conversion rate and degradation products of ANT were investigated in different concentrations of Tween 80 solution.
