“…The studies demonstrated that the results achieved possess optimal values for specific parameters of magnetic water treatment, where for example a change of content of calcium ions in water depends on the length of the pathway in the field and the flow rate (Gabrielli et al, 2001). Application for water disinfection of permanent magnetic and electrical fields causes a significant decrease of microorganismal and bacterial content (Biryukov et al, 2005). Research carried out over the years concerning the possibility of the application of magnetically treated water in agriculture has generally been concerned with determining of its usefulness for improving seed germination and plant growth (Morejon et al, 2007).…”

“…Applying the 'free dipole' model, in which Lorenz strength acts in the magnetic field, causing the T a b l e 3. Final plant mass obtained after germination polarization of the water molecules, it is possible to explained the changes in water properties and impurities contained therein, and the activity of microorganisms present in the water having an impact on seed germination of and plant development (Biryukov et al, 2005). The largest value of the maximum rate of germination, v max , achieved thanks to logistic curve modeling for interaction with magnetic field occurred for sample P2 (MF 30 s), while for P1 (MF 15 s) it was the lowest, where the impact on germination rate was negative relative to the control sample (Table 4).…”

A b s t r a c t. The impact of a variable magnetic field, magnetically treated water and a combination of both these factors on the germination of seeds and the final mass at the initial stage of growth sunflower plants was presented. Investigations were carried out in pots filled with sand, tin an air-conditioned plant house with no access to daylight using fluorescent light as illumination. A statistical significance positive impact was achieved for the samples subjected to the interaction of both stimulating factors simultaneously, the magnetic field and the impact of treated water several times on the speed of seed germination and final plant mass. Negative impacts were obtained for the majority of the test cases, for the magnetically treated water, the short duration of activity of the magnetic field and for the connection of the magnetic field and low-flow times.K e y w o r d s: seed stimulation, magnetic field, magnetically treated water

“…Magnetized water causes an increase of permeability of cell membranes to calcium ions and inhibition of the growth of pathogenic microorganisms. Treatment with magnetized water also causes an increase of electric conductivity and a decrease of surface tension (Goldsworthy et al 1999;Coey & Cass 2000;Biryukov et al 2005). In the study conducted by Goldsworthy et al (1999), weakly conditioned water with pulsed 100 kHz electromagnetic field for 5-30 s stimulated the growth of yeast cultures.…”

“…It activates cell division in plant tissue and affects the elongation of cells (Murphy 2006). There is no evidence that IAA participates in the germination process or in the radical emergence, but later eventsseedling growthmight be controlled by the hormone (Bewley & Black 1985). It appears that an increased level of IAA in seedlings, resulting from pre-sowing irradiation of seeds, may determine stronger dynamics of growth of crop plants.…”

Due to the common trend towards limitation of excessive use of chemicals in agriculture, there is a growth of interest in methods of seed quality improvement that would be safe for the environment. These include methods based on the effect of various physical factors, such as laser light, magnetic field, seed treatment with magnetized water, electric field. The work provides detailed information on the impact of seed stimulation of these factors on germination, growth, development and yielding of horticultural plants. Summarizing the results of the study, it can be concluded that the application of physical factors in appropriate doses can be an effective way to enhance many plant parameters that increase their productivity. The beneficial effects of seed stimulation are mainly related to the first stages of plant life, i.e. – germination, emergence and growth of seedlings. In many cases, the enhancement of these features is also the result of the increase of plant yields. The increase of yield is even several dozen percent. The results of the study encourage the implementation of these physical methods of seed quality improvement into agricultural and horticultural practice.

Electrogeneration of hydrogen peroxide in seawater and application to disinfection

2008

View full text Add to dashboard Cite

The cathodic electrogeneration of hydrogen peroxide in seawater by means of oxygen reduction on a gas diffusion cathode was studied. The effects on the reaction yield of several operative parameters such as cell design, medium composition, anolyte concentration, pH and working potential were investigated. Results indicate that in a two-compartment cell notable concentrations of hydrogen peroxide are obtained with a constant yield in a wide range of charge. Lower catholyte pH values, obtainable by means of the anolyte choice, mitigate the decrease in the efficiency due to cathode fouling. Application of hydrogen peroxide electrogeneration to seawater disinfection was also tested. Comparative tests conducted using both commercial and electrogenerated hydrogen peroxide, either alone or combined with iron in Fenton's treatment, are also presented
