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

　　The technique of a complex developing a cyclic framework in which a main ion and 2 or more coordinating atoms the exact same polydentate ligand of certain situations are bonded is named chelation. The consequence of the hydrazine cooperation is the scale-developing cations (such as ca2 , Mg2 , and so on.) interact with the chelating broker to make a dependable chelate, therefore preventing it from developing a range anion (like co32-, 5042, 51032, one and Po4, and Sequestering agents so forth.

　　The make contact with helps make the probability of range development reduced. Chelation is conducted stoichiometrically, for example one particular EDTA molecule incorporating a single divalent metallic ion. The ability from the chelating broker to combine could be expressed through the calcium mineral chelation benefit. The chelating capability of your business h2o therapy broker (this is 50Percent in the active aspect of every professional, as well as the chelating capacity is calculated by CaCO3): aminotrimethylene linonic acid solution (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acid (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acid (EDTA) - 15om years g: prolonged by phenylethyl bis-linic acid solution (HEDP) - 45om.

　　In assessment, 1 milligrams of chelating agent are only able to chelate below .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 might be noticed how the involvement of size inhibitor chelation is simply a tiny component of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
