Researches On The Morphological Of PFS Under Effect Of Electromagnetic Field

Electromagnetic field is not only a kind of physical field which has a cross fade betweenmagnetic field and electric field with a constant amplitude and frequency. Electromagnetic fieldcan enhance the activity of water molecules, and can affect the pH, electrical conductivity andother physical and chemical properties. Taking this electromagnetic field which of polarizationeffect, hysteresis effect, changing the hydrogen bond and increasing the activity of watermolecules to the coagulant will tend to affect the hydrolysis of coagulant. In this paper,homemade AC frequency conversion magnetization assembly is used to magnetize polymericferric sulfate solution by changing its frequency, Voltage, current and magnetizing time. UsingFe-Ferron complexation colorimetry, ultraviolet spectroscopy, transmission electronmicroscopy method and other testing means hourly analysis the morphology of the magnetizedpolymeric ferric sulfate, and then compared with the non-magnetized polymeric ferric sulfate toexplore the reason of its morphological change. It also in Vestigates the coagulation propertiesof the magnetized polymeric ferric sulfate solution through beaker coagulation experiment andanalyzes its coagulation mechanism. This paper researches the following aspects：To understand the stability of polymeric ferric sulfate, this paper has done the water bathtest and determined PH of polymerization iron sulfate solution under the action of alternatingmagnetic field under the action of alternating magnetic field can be determined through waterbath test and polymeric ferric sulfate solution pH value and conductivity of the stability ofpolymeric ferric sulfate. Results show that the precipitation capacity of polymeric iron sulfateunder the action of alternating magnetic field In the water bath test is much lower than theprecipitation capacity unmagnetized polymeric iron sulfate. By the water bath test pH value andconductivity have also improved significantly and improved the stability of polymeric ferricsulfate.This paper has studied the shape of the polymeric ferric sulfate under the action of theelectromagnetic field by using Fe-Ferron hourly complexing colorimetric method, ultravioletabsorption/visible spectroscopy and Transmission electron microscopy. The results prove that:The formation distribution of polymeric ferric sulfate is changed under the action of alternatingmagnetic field; Feb plays a main role of the coagulation in magnetized polymeric ferric sulfate and the content of this Feb is more than unmagnetized. The average percentage increases36%and the percentage content of Feb will achieve the maximum when300HZ frequency,100vvoltage,0.8A current and magnetization time for2min. the content of this Feb is2times ofunmagnetized polymer ferric sulfate and changing frequency largest impacts on Feb percentagecontent. The absorption value of polymeric ferric sulfate solution under the influence ofelectromagnetic field is higher than unmagnetized polymer ferric sulfate whenultraviolet-visible spectrum at240-340nm.That shows Hydroxy complex content of low ormoderate degree of polymerization improved; Compared with unmagnetized polymer ferricsulfate, In addition to,Chain distribution structure of polymeric ferric sulfate under the action ofalternating magnetic field is much larger and mostly tend to mesh structure and continuousclose; Also has the phenomenon that polymer size increased and the polymerization degreeenhanced.By coagulation experiment to discuss the coagulative performance of Polymeric FerricSulfate was under the action of alternating magnetic field. Results show that turbidity of treatedwater of coagulation and COD value by magnetization is lower50%than that unmagnetizedunder the same quantity of reagent.This proves that electromagnetic field can improve theflocculation performance of the polymeric ferric sulfate.
