Abstract
[C]ethylenediaminetetraacetate (EDTA) was shown to be slowly biodegraded to CO(2) in soils and sediments under aerobic conditions and by microorganisms in mixed liquid culture. EDTA chelates of Cu, Cd, Zn, Mn, Ca, and Fe added to soil were equally degraded, while Ni-EDTA was degraded more slowly.
摘要
[C]在有氧条件下，土壤和沉积物中的乙二胺四乙酸（EDTA）被证明会缓慢生物降解为二氧化碳，并且在混合液体培养中会被微生物降解。添加到土壤中的铜、镉、锌、锰、钙和铁的EDTA螯合物被同等程度地降解，而镍-EDTA的降解则更慢。
