Specifications & selection
Specifications and order requirements
Discuss your current grade or operating conditions. ENVO codes identify sales requirements; manufacturer grades, supply specifications, test methods and document versions are confirmed for the selected product.
ENVO-EDTA-H99Catalogue EDTA-acid grade
Catalogue EDTA assay ≥99.0%; test basis requires the current document.
Application conditions & technical scope
Chelation controls metal ions; it does not separate heavy metals from wastewater. Assess acid-form dissolution and formulation pH conditions separately.
Appearance and supplied form
Confirm the form before comparing specifications.
Check the required form, then compare the composition, specifications and test conditions of the specific grade.
Product forms to compare

Application issues and troubleshooting
Ethylenediaminetetraacetic Acid — troubleshooting checks
Review symptoms, possible causes and verification steps together to prepare a more focused product-selection discussion.
01EDTA dissolution or formulation pH differs from expectations
- Possible causes
- Acid/sodium-salt form, hydration state or formulation conditions may differ.
- Investigation and resolution
- Confirm acid/salt and water-of-crystallization bases first; compare dissolution under the same formulation conditions.
- Checks required
- Actual chemical identity, assay basis, preparation-water quality, pH and process.
- Application limits
- EDTA acid, disodium and tetrasodium salts are not interchangeable at equal mass.
02Metals remain in the water after adding a chelant
- Possible causes
- Chelation changes metal speciation; it does not itself precipitate or remove metals.
- Investigation and resolution
- Distinguish metal-control formulations from wastewater removal. Assess decomplexation/capture and downstream separation separately for complexed metals.
- Checks required
- Metal valence, chelants, COD and existing reaction/separation process.
- Application limits
- Do not market a chelant directly as a heavy-metal removal agent or a discharge guarantee.
03EDTA acid purity data do not directly predict formulation performance
- Possible causes
- Moisture, impurities and test methods differ; formulation acidity/alkalinity also affects dissolution and metal binding.
- Investigation and resolution
- Align acid-form assay measurement and testing bases, then compare dissolution and complexation under formulation conditions.
- Checks required
- Current product information, assay/moisture methods, metal ions, formulation pH and insoluble-matter requirements.
- Application limits
- Assess EDTA acid separately from sodium salts; a high purity figure cannot establish process compatibility.

Ethylenediaminetetraacetic Acid: EDTA dissolution or formulation pH differs from expectations — what should I check?
Confirm acid/salt and water-of-crystallization bases first; compare dissolution under the same formulation conditions.
What should I compare when buying Ethylenediaminetetraacetic Acid?
Share the application, current product, purchase quantity and delivery location to help confirm a suitable specification. Key checks include: Content & reporting basis; Dissolution conditions; Iron & other impurities; Chelation value units & method. Compare the current grade document and the same test basis before choosing an alternative.
Which documents should accompany a Ethylenediaminetetraacetic Acid enquiry?
Request the current grade-specific TDS and product SDS, the COA for the actual supplied batch, and any intended-use documents required for the destination. Share the application, specification, quantity and delivery requirements. Document version, batch coverage and public-release scope are confirmed for the specific request.
