The chelation of scale inhibitors may be less known, although 　　Speaking of scale inhibitors, I believe that everyone is no stranger. Nowadays, Xiaobian will explain regarding the chelation of range inhibitors.

　　The procedure of a complicated possessing a cyclic construction in which a key ion and several coordinating atoms of the identical polydentate ligand of specific problems are bonded is called chelation. Caused by the hydrazine assistance would be that the level-developing cations (including ca2 , Mg2 , etc.) react with the chelating professional to create a stable chelate, thereby protecting against it from generating a range anion (such as co32-, 5042, one, Po4 and 51032, and many others.

　　The make contact with can make the odds of size creation reduced. Chelation is performed stoichiometrically, such as one EDTA molecule mixing 1 divalent metal ion. The capacity of your chelating representative to bind may be depicted from the calcium chelation benefit. The chelating ability of your professional h2o therapy representative (this is 50Percent from the energetic element of every broker, and also the chelating capacity is measured by CaCO3): aminotrimethylene linonic acidity (ATMP) - 300 milligrams / g: diethylene triamine Pentamethyl lincosic acid solution (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acidity (EDTA) - 15om yrs old g: expanded by phenylethyl bis-linic acidity (HEDP) - 45om.

　　In assessment, Sequestering agents 1 mg of chelating representative could only chelate below .5 mg of CaCO3. If the calcium and magnesium 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 could be seen that this contribution of level inhibitor chelation is just a modest part of it. However, in medium and low hardness water, it is still the sequestration of scale inhibitors.
