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

　　The procedure of an intricate using a cyclic framework in which a key ion and several coordinating atoms of the same polydentate ligand of certain conditions are bonded is named chelation. Caused by the hydrazine assistance is the range-generating cations (like ca2 , Mg2 , and so on.) interact with the chelating representative to form a steady chelate, thereby stopping it from creating a range anion (for example co32-, Po4, one, 51032 and 5042, and so forth.

　　The contact tends to make the probability of range formation greatly reduced. Chelation is carried out stoichiometrically, including a single EDTA molecule merging one particular divalent steel ion. The power from the chelating agent to combine could be conveyed through the calcium supplement chelation importance. The Organophosphine Chelating agent capability from the professional normal water therapy professional (this is 50% from the productive part of each professional, as well as the chelating ability is calculated by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acid solution (DTPMP) - 450 milligrams / g: ethylenediaminetetraacetic acid solution (EDTA) - 15om yrs old g: extended by phenylethyl bis-linic acid solution (HEDP) - 45om.

　　In evaluation, 1 mg of chelating professional are only able to chelate under .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 might be observed that this participation of range inhibitor chelation is just a little element of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
