Combination of hydrodechlorination and biodegradation for the abatement of chlorophenols

, 2012
A method for abatement for chlorophenols (CPs) in contaminated water based on successive steps of catalytic hydrodechlorination (HDC) over Pd/C at ambient temperature and pressure, followed by aerobic biodegradation using yeast Candida tropicalis (C ...
