Abstract
Treatment of aqueous solutions and biological objects vegetable magnetic field - a promising technology that can not only increase the yield of crops, destroy pathogens, improve fertilizer use, but also affect the biosynthesis, intensify the anaerobic processes of waste biomass into biofuel and fertilizer. Now the theory of magnetic treatment of water systems is under nomination and substantiate hypotheses, although experimentally established that magnetic water treatment alters its physical and chemical properties. But the lack of explanation of the effect of the magnetic field on processes occurring in aqueous solution does not make it possible to establish all the factors in its treatment in a magnetic field and to determine their optimal values. The purpose of the study is to determine the influence of the magnetic field on the change of pH and ORP of aqueous solutions. Experimental studies of changes in the parameters of aqueous solutions during processing in a magnetic field were carried out on a laboratory installation. Solutions were allowed in Petri dishes through a magnetic field created by permanent magnets. The magnetic induction was controlled by changing the distance between the magnets and measured with a tetrameter 43205/1. The velocity of the conveyor belt with the petri dish placed on it was adjusted with the solution by changing the frequency of rotation of the drive motor of the conveyor with the help of a frequency converter. The oxidation-reduction potential (ORP) and the pH of the aqueous solution were determined prior to the magnetic treatment of the solution and after it using the i-160M ionizer. The research was carried out using the experiment planning method. The value of the upper, lower and main levels accounted for magnetic induction respectively 0, 0.065 and 0.13 T, to the velocity of the water and fertilizer solutions - 0.4, 0.6 and 0.8 m/s. Experimentally that when the magnetic induction from 0 to 0,065 T pH in aqueous solutions is growing, and with further increase of magnetic induction begins to decrease. When the magnetic induction is changed from 0 to 0.065 T, the ORP solution decreases, and with subsequent increase in the ORP increases. A larger change in the ORP occurred at lower flow velocities, although the velocity of the solution is less significant than the magnetic induction. The effect of magnetic processing also depends on the speed of the solution, the number of reversal and the chemical composition of the solution, i.e. concentration and composition of the ions. In a solution containing ions of water structure-stabilizers (Ca2+, Mq2 +, SO42-), it is more noticeable than in solutions with ions that are "fluff" around him water structure (K+, NO3-). The increase in the number of reversal magnifies the effect of magnetic processing of water). An optimal four-time re-magnetization can be considered, since its growth does not lead to a significant change in water parameters (the change in pH does not exceed 0.01, while the ORP is 1 mV). When processing aqueous solutions in a magnetic field, the rate of chemical reactions changes, the degree of electrolytic dissociation increases, which helps to better dissolve salts and acids. The effect of treatment of water and solutions of fry depends on the square of the magnetic induction, the velocity of the solution in the magnetic field and its chemical composition. The most effective treatment of aqueous solutions in a magnetic field is the magnetic induction of 0.065 T, with a four-time re-magnification and a velocity of 0.4 m/s.
