Uses:-tetrasodium glutamate diacetate is widely used in chemical analysis, industrial production and medical fields. - in chemical analysis, it can be used to control the concentration of metal ions in order to avoid interference between metal ions. - It can also be used as passivating agent, antirust agent and cleaning agent for metal ions. Preparation method:-tetrasodium glutamate diacetate can be prepared by the reaction of glutamic acid and acetic acid. The specific preparation method is to make a mixed solution of glutamic acid and acetic acid, and then carry on the replacement reaction of acetate ion under the alkaline condition, finally obtain the glutamic acid tetrasodium diacetate. Safety information:-tetrasodium glutamate diacetate is generally considered to be relatively safe and does not require special precautions under normal use conditions. - as a chemical, however, care should be taken to avoid inhalation of powder, contact with skin or eyes. - avoid contact with strong acids or oxidants during treatment to prevent reactions. - in case of accidental exposure, seek medical attention immediately.
