Usage
- Ethylenediaminetetraacetic acid is used as a treatment for acute lead poisoning.
- In laboratory research, ethylenediaminetetraacetic acid is added to samples to prevent metal ions from interfering with reactions.
- The stability constant of the complex formed by ethylenediaminetetraacetic acid and calcium is very high.
Advanced Usage
- "EDTA therapy": A medical treatment involving the administration of ethylenediaminetetraacetic acid or its salts to remove toxic metals.
- The patient underwent EDTA therapy for heavy metal detoxification.
- "EDTA anticoagulant": The use of ethylenediaminetetraacetic acid salts in blood collection tubes to prevent clotting by binding calcium ions.
