EDTA SOLUTION 40 percent
Product code RXSOL-33-6604-230
Tetrasodium Ethylenediaminetetraacetate is a powerful chelating and sequestrating agent.
Description
RXSOL Tetrasodium EDTA 40% Liquid is a concentrated aqueous solution of tetrasodium ethylenediaminetetraacetate (Na₄EDTA), a powerful chelating and sequestrating agent.
It binds polyvalent metal ions such as calcium, magnesium, iron, copper and other metal ions, converting them into stable water-soluble complexes. This helps prevent precipitation and assists in removing mineral and metallic deposits during industrial cleaning.
The product is particularly useful in reverse osmosis (RO) membrane cleaning/CIP, where EDTA can assist in removing metal-containing deposits and certain inorganic/organic foulants. DuPont's FilmTec RO/NF technical manual specifically lists 1.0 wt% Na₄EDTA with 0.1 wt% NaOH as an alternative cleaning solution for biofouling, subject to membrane compatibility and the manufacturer's cleaning limits.
Application
Manufacturing, EDTA is used to improve stability of some pharmaceutical products, detergents, liquid soaps, shampoos, agricultural chemical sprays, contact lens cleaners and cosmetics. It is also used in certain blood collection tubes used by medical laboratories.
