Abstract
Abstract
This study reports on the first assessment of the treatment of sediment contaminated by organotin compounds using homogenous and heterogeneous photocatalysis. Photo-Fenton and photocatalysis of low level (µg/L) organotins in water were carried out. A quasi-complete degradation of tributyltin (TBT) in water (99.8%) was reached after 30 and 7 min for photocatalytic and photo-Fenton treatment, respectively. For the first time decontamination of highly polluted marine sediments by photo-oxidation proves that the use of UV and the production of hydroxyl radicals are an efficient way to treat organotins adsorbed onto marine sediment despite the complexity of the matrix.
