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 concerning the chelation of level inhibitors.

　　The procedure of a complicated possessing a cyclic framework in which a central ion and two or more coordinating atoms the exact same polydentate ligand of specific conditions are bonded is called chelation. The consequence of the hydrazine assistance is that the level-developing cations (for example ca2 , Mg2 , and many others.) interact with the chelating representative to make a stable chelate, thereby stopping it from developing a size anion (like co32-, Po4, one, 51032 and 5042, and many others.

　　The speak to makes the prospect of range creation greatly reduced. Chelation is conducted stoichiometrically, for example a single EDTA molecule incorporating a single divalent metal ion. The ability in the chelating professional to combine might be depicted from the calcium supplement chelation worth. The chelating ability in the commercial normal water treatment method professional (this is 50Percent of the energetic aspect of each and every professional, and also the chelating potential is calculated by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acid solution (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acid solution (EDTA) - 15om yrs old g: extended by phenylethyl bis-linic acid solution (HEDP) - 45om.

　　In comparing, 1 mg of chelating professional are only able to chelate below .5 milligrams of CaCO3. The required chelating agent is l000 m Guo L, which is economically unacceptable, if the calcium and magnesium ions with a total hardness of smm0FL are to be stabilized in the circulating water system. It may be viewed that this involvement of range inhibitor chelation is only a little component of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
