USAGE

1.This product is chelating titrant. It is used as a complexing agent for the treatment of radioisotope and heavy metal poisoning. Complexing agent. Complexation titration of molybdenum, sulfate and rare earth metals, titration of copper by current titration.

2.DTPA is an important amino chelating agent, thus has an important application in the cleaning industry.DTPA has complexing or chelating effect on calcium, magnesium and iron scale-forming ions, with good solution effect.

3. Used as defoamer in pulp, paper, sewage treatment, metal cutting fluid and water-based paint. Especially in the pulp and paper industry, it can eliminate floating pulp, and can improve the washing speed, washing quality and bleaching quality, reduce the loss of good pulp, and eliminate the spots, transparent points, holes and eyes on the paper surface. It has good defoaming effect.

4. Used in paper bleaching process, as hydrogen peroxide decomposition inhibitor.
