Abstract
In this study, we examined the removal and decomposition efficiencies of regenerated amorphous iron oxide on tributyltin (TBT) and triphenyltin (TPT). The results indicated that removal capacity could be estimated from Freundlich function, and also that half-life period of TPT by contact with the iron oxide at 20 °C was 3.1 hours, which was from one hundredth to one tenth in comparison with natural environment condition. Furthermore, the romoval rate of TBT and TPT on the treatment of high polluted sea water made from actual polluted sediment were 80% and 97% respectively. These observations indicate that this iron oxide is useful for treatment of organotin compounds in seawater.
