Toxicity
THE GROWTH OF WASTE VOL IN COMPLEXANT LADEN HANFORD WASTE SLURRY WAS DUE TO GAS GENERATION CAUSED BY THE OXIDATIVE DEGRADATION OF THE COMPLEXANT HEDTA. THE DEGRADATION PROCEEDS ACCORDING TO 1ST ORDER KINETICS & REQUIRES NITRATE AND/OR NITRITE TO PROCEED.
Drug Information
Chelating Agents|EXPTL USE: ISOLATED CELL ENVELOPES OF SOME BETA-LACTAMASE POS AND NEG STRAINS OF GRAM-NEG BACTERIA WERE EXPOSED TO CHELATING AGENTS. ENVELOPES FROM PSEUDOMONAS AERUGINOSA CONTAINED GREATEST AMOUNTS OF MG(2+) & WERE MOST SENSITIVE TO THESE AGENTS IN TERMS OF LYSIS, RELEASE OF CATIONS, & RELEASE OF READILY EXTRACTABLE LIPID. CYCLOHEXANE-1,2-DIAMINETETRAACETIC ACID WAS THE MOST EFFECTIVE CHELATOR, FOLLOWED BY EDTA AND HEDTA.|EXPTL USE: MALE RATS WERE INJECTED IP WITH (241)AMERICIUM, THEN ADMINISTERED IN DIFFERENT MODES THE ZINC CHELATES OF DECONTAMINATION AGENTS. HEDTA WAS EXAMINED.|EXPTL USE: HEDTA WAS HIGHLY SUCCESSFUL IN ENHANCING EXCRETION AND REDUCING TISSUE LEVELS OF (54)MN IN RATS AFTER ADMIN OF (54)MNCL2.|For more Therapeutic Uses (Complete) data for HYDROXYETHYLETHYLENEDIAMINETRIACETIC ACID (6 total), please visit the HSDB record page.
Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS. (See all compounds classified as Chelating Agents.)

< 25,000 lb
All other basic organic chemical manufacturing|Glycine, N-[2-[bis(carboxymethyl)amino]ethyl]-N-(2-hydroxyethyl)-: ACTIVE|AN AQ SOLN CONTAINING HEDTA WAS USED TO TREAT WASTE GASES FROM A XANTHATE PROCESS. THE HYDROGEN SULFIDE REMOVAL EFFICIENCY WAS 80-95%.|HEDTA STABILIZED A 1% AQ SOLN OF CHLORPROMAZINE HYDROCHLORIDE, PROMAZINE HYDROCHLORIDE, AND TRIFLUPROMAZINE HYDROCHLORIDE.|HEDTA IN A VERY LOW CONCN (O.5 MMOL/L) AFFORDS A DEFINITIVE INHIBITORY EFFECT ON THE RATE OF THIAMINE HYDROCHLORIDE CLEAVAGE.|HEDTA STABILIZED ISONIAZID SOLUTIONS.|HEDTA IS USED TO SEPARATE STRONTIUM FROM OTHER FISSION PRODUCTS IN AN ANALYTICAL PROCEDURE.
