The present invention relates to series of compounds with aqueous metal decontamination activity and their uses in removing metals from aqueous media. The compounds are esters of organic acids or alcohols with polyols that contain a sulfhydral group (—SH). The compounds release sulfhydral slowly into the water providing activity over extended periods of time and exhibit biodegradable characteristics. The compounds may be used to remediate aqueous media.
本发明涉及一系列具有水相金属去污活性的化合物及其在从水相介质中去除金属方面的用途。这些化合物是含有硫醇基(—SH)的多元醇的有机酸或醇酯。这些化合物缓慢地释放硫醇到水中,从而提供长时间的活性,并表现出可生物降解的特性。这些化合物可用于修复水相介质。
