Patent abstract

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.
