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

　　The procedure for a complex having a cyclic composition in which a core ion and a couple of coordinating atoms the exact same polydentate ligand of specific circumstances are bonded is named chelation. The effect of the hydrazine cohesiveness is the scale-creating cations (for example ca2 , Mg2 , and so on.) interact with the chelating representative to make a secure chelate, thus protecting against it from creating a level anion (such as co32-, Po4, 5042, one and 51032, and so on.

　　The get in touch with can make the odds of size creation reduced. Chelation is conducted stoichiometrically, like one particular EDTA molecule mixing a single divalent metallic ion. The capacity of the chelating agent to combine could be indicated through the calcium supplements chelation worth. The chelating ability of the industrial water treatment broker (the following is 50Per cent in the energetic aspect of every single representative, as well as the chelating ability is determined by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 milligrams / g: diethylene triamine Pentamethyl lincosic acidity (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acidity (EDTA) - 15om years g: extensive by phenylethyl bis-linic acid solution (HEDP) - 45om.

　　In assessment, 1 milligrams of chelating representative are only able to chelate lower than .5 mg 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 could be observed that the contribution of range inhibitor chelation is only a tiny part of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
