El EDDS tris\u00f3dico es un agente quelante.
El agente quelante tambi\u00e9n se denomina agente secuestrante\/enmascarante, agente complejante\/quelante.<\/p>\n\n\n\n

Especialmente en sistemas de agua dura, el EDDS sigue siendo excelente para quelar iones de metales de transici\u00f3n (por ejemplo, Fe3+, Cu2+), antes de quelar iones de agua dura (calcio, magnesio).<\/p>\n\n\n\n

EDDS trisodium is an chelating agent (sequestering\/complexing agent).
Especially in hard water systems, EDDS is still excellent at chelating transition metal ions (e.g. Fe3+<\/sup>, Cu2+<\/sup>), before chelating hard water ions (calcium, magnesium).<\/p>\n\n\n\n

Features:<\/strong><\/p>\n\n\n\n

    \n
  1. In hard water, relative to calcium and magnesium ions, it still has high selectivity<\/strong> for transition metal ions such as copper and iron.<\/li>\n\n\n\n
  2. Within a wide pH range<\/strong>, EDDS can effectively complex and sequester heavy metals such as Fe3+<\/sup>, Cu2+<\/sup>, and Ca2+<\/sup>, Mg2+<\/sup>.<\/li>\n\n\n\n
  3. High thermal<\/strong> stability, high stability in concentrated alkaline<\/strong> solutions.<\/li>\n<\/ol>\n\n\n\n

    Main functions:<\/strong><\/p>\n\n\n\n

      \n
    1. It has high selectivity<\/strong> for copper and iron ions. In the presence of calcium and magnesium, transition metal ions such as copper, and iron ions are still preferentially chelated.<\/li>\n\n\n\n
    2. Reduce the impact of water hardness in formula or process use, and improve the compatibility<\/strong> of hard water.<\/li>\n\n\n\n
    3. Improve the effectiveness of fungicides<\/strong> in the formula.<\/li>\n\n\n\n
    4. Prevent discoloration and odor. Improve antioxidant properties, reduce the oxidation catalysis of heavy metals on fatty acids, and prevent odor and discoloration.<\/li>\n\n\n\n
    5. High stability, suitable for wide pH values, resistant to strong alkaline environments, and resistant to high temperatures.<\/li>\n\n\n\n
    6. Environmentally friendly chelating agent, easy to biodegradable and easy to rinse.<\/li>\n<\/ol>\n\n\n\n
