The chelation of scale inhibitors may be less known, although Speaking of scale inhibitors, I believe that everyone is no stranger. Nowadays, Sequestering agents Xiaobian will explain regarding the chelation of scale inhibitors.
The procedure of a complicated developing a cyclic structure in which a main ion and 2 or more coordinating atoms the exact same polydentate ligand of specific problems are bonded is named chelation. The consequence of the hydrazine cohesiveness would be that the scale-forming cations (such as ca2 , Mg2 , and so forth.) react with the chelating broker to create a steady chelate, thus preventing it from developing a level anion (like co32-, one, 5042, 51032 and Po4, and many others.
The speak to can make the possibilities of level development reduced. Chelation is performed stoichiometrically, including a single EDTA molecule mixing one divalent steel ion. The power of your chelating representative to combine can be depicted by the calcium mineral chelation worth. The chelating ability in the industrial normal water remedy agent (this is 50Per cent from the productive element of each and every professional, and also the chelating capability is determined by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 mg / g: diethylene triamine Pentamethyl lincosic acid (DTPMP) - 450 milligrams / g: ethylenediaminetetraacetic acidity (EDTA) - 15om years old g: extended by phenylethyl bis-linic acid solution (HEDP) - 45om.
In comparing, 1 mg of chelating representative is only able to chelate under .5 mg of CaCO3. The required chelating agent is l000 m Guo L, which is economically unacceptable, if the magnesium and calcium ions with a total hardness of smm0FL are to be stabilized in the circulating water system. It may be noticed that the participation of scale inhibitor chelation is just a small part of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
