  How much EDTA or citric acid minimum required to remove iron from water?

  Posted by Abdullah on January 16, 2022 at 12:59 pm

  I want to make a simple 1% sodium salicylate solution with a cationic surfactant. The problem is the iron in water changes the color of solution so i need a chelating agent for iron but the cationic surfactant forms insoluble salt with chelating agents. 

  I have tried even 0.008% EDTA and it still produced insoluble salt. 

  My question is: what is the minimum amount of EDTA or citric acid required to remove iron from water?
