Removal of Lead from Contaminated Soils with Chelating Agents
The biodegradable chelating agents [S,S]-ethylenediaminedisuccinic acid (EDDS), citric acid and the low biodegradable chelating agent ethylenediaminetetraacetic acid (EDTA) were investigated for their applicability for the removal of lead from soil by soil washing and electrokinetic processing. In the soil washing tests at 298K, the removal efficiency of lead with EDDS and EDTA was high in the ...
متن کاملRemoval of Heavy Metal from Contaminated Soil with Chelating Agents
Removal of copper and nickel by the addition of the biodegradable chelating agent, chitosan and ethylenediamine tetraacetic acid (EDTA), was investigated, alongside the reaction of a reference compound sodium citrate for comparison. The artificial-contaminated soils were used in this study. The experiments showed that the extraction ability for copper and nickel from the contaminated soil decre...
متن کاملRemoval of nano- and micronized-copper from treated wood by chelating agents
Micronized and nano-copper (Cu)-based and arsenic and chromium-free systems have received much attention for wood protection in recent years. Because they have different fixation, and micro-distribution properties, such copper systems may be more or less subject to release using known remediation methods than soluble forms of Cu. This study evaluated Cu recovery from wood treated with micronize...
متن کاملDesign of therapeutic chelating agents.
The successful design of orally active non-toxic selective metal chelators is a much sought-after goal. In order to identify an ideal chelator for clinical use, a range of specifications must be considered, such as metal selectivity and affinity, kinetic stability of the complex, bioavailability and toxicity. In this overview the comparative properties of ligands capable of endowing complexes w...
