环境友好型海洋防污剂的性能研究

Study on the Performance of Environment-friendly Marine Antifouling Agent

综述对比了三丁基锡(TBT)与Sea-Nine 211作为海洋防污剂在防污性能以及环境影响等方面的效果。Sea-Nine可以被微生物迅速降解,其好氧及厌氧条件下的半衰期均小于1 h。Sea-Nine的降解产物为开环衍生物,其毒性已大大降低。TBT降解的产物之一为二丁基锡衍生物,仍然具有毒性并且在环境中不易降解。

This paper narrates and compares the antifouling property and the influence on the environment between TBT and Sea- Nine211 as the marine antifouling agents. Sea-Nine can be rapidly degraded by microorganism and the half-life is all shorter than 1 h either under the aerobic conditions or under anaerobic conditions. Degradation product of Sea-Nine is ring opening derivatives and the toxicity is greatly reduced. One of degradation product of TBT is dibutyltin derivatives, being still of toxicity and inclined to degrading.
