The chelation of scale inhibitors may be less known, although 　　Speaking of scale inhibitors, I believe that everyone is no stranger. Today, Xiaobian can tell you regarding the chelation of size inhibitors.

　　The procedure of a complicated possessing a cyclic composition in which a key ion and a couple of coordinating atoms of the same polydentate ligand of certain problems are bonded is named chelation. The effect of the hydrazine cooperation would be that the level-forming cations (for example ca2 , Mg2 , and so forth.) interact with the chelating broker produce a steady chelate, and thus protecting against it from forming a range anion (such as co32-, 51032, Po4, 5042 and one, etc.

　　The make contact with makes the odds of size creation greatly reduced. Chelation is performed stoichiometrically, for example a single EDTA molecule merging 1 divalent metal ion. The capacity of the chelating representative to bind can be conveyed through the calcium supplements chelation benefit. The chelating capacity from the industrial drinking water treatment method representative (this is 50Per cent of your productive aspect of every single broker, as well as the chelating ability is determined by CaCO3): aminotrimethylene linonic acid solution (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acid (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acid (EDTA) - 15om years of age g: extensive by phenylethyl bis-linic acidity (HEDP) - 45om.

　　In comparison, 1 mg of chelating representative is only able to chelate under .5 milligrams of CaCO3. If the magnesium and calcium ions with a total hardness of smm0FL are to be stabilized in the circulating water system, the required chelating agent is l000 m Guo L, which is economically unacceptable. It might be viewed how the contribution of range inhibitor chelation is simply a little element of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
