Speaking of scale inhibitors, I believe that everyone is no stranger, but the chelation of scale inhibitors may be less known. These days, Xiaobian will tell you about the chelation of range inhibitors.

　　The process of a complex using a cyclic framework wherein a central ion and 2 or more coordinating atoms of the same polydentate ligand of certain circumstances are bonded is named chelation. The result of the hydrazine collaboration is that the level-developing cations (such as ca2 , Mg2 , and so on.) interact with the chelating broker to create a stable chelate, thus preventing it from creating a level anion (including co32-, one, Po4, 5042 and 51032, and many others.

　　The speak to can make the possibilities of range development cut down tremendously. Chelation is performed stoichiometrically, like one EDTA molecule combining one particular divalent steel ion. The ability in the chelating representative to bind could be expressed from the calcium chelation benefit. The Organophosphine Chelating agent capability of the business water treatment method broker (this is 50% from the energetic component of every single representative, as well as the chelating potential is calculated by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acidity (DTPMP) - 450 milligrams / g: ethylenediaminetetraacetic acid (EDTA) - 15om years of age g: expanded by phenylethyl bis-linic acid (HEDP) - 45om.

　　In comparison, 1 milligrams of chelating professional can only 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 can be seen the involvement of level inhibitor chelation is simply a modest part of it. However, in medium and low hardness water, it is still the sequestration of scale inhibitors.
