“…The effect of static magnetic and electromagnetic fields (EMF) on water or on the behavior of aqueous solutions and suspensions has increasingly drawn the attention of investigators in recent years [1][2][3][4][5] . For instance, it has been shown that water exhibits changes in physicochemical properties in response to variations of field intensity and/or frequency 4,5 .…”

“…For instance, it has been shown that water exhibits changes in physicochemical properties in response to variations of field intensity and/or frequency 4,5 . The idea of a change in the structure of water itself, as a result of magnetic exposure has been criticized due to the low energy from the used field intensities in comparison with the one from thermal agitation.…”

The effects of a pulsed low frequency electromagnetic field were investigated on photoluminescence of well characterized water and prepared under controlled conditions (container, atmospheric, electromagnetic, and acoustic environments). When reference water samples were excited at 260 nm, two wide emission bands centered at 345 nm (3.6 eV) and 425 nm (2.9 eV) were observed. By contrast under 310 nm excitation, only one band appeared at 425 nm. Interestingly, electromagnetic treatment (EMT) induced, at both excitation wavelengths, a decrease (around 70%) in the 425 nm band relative photoluminescence intensity. However, no difference between reference and treated sample was observed in the 345 nm band. Other experiments, performed on outgassed samples (reference and treated), show that the emission bands (position, shape, intensity) under excitation at 260 nm and 310 nm were similar and close to the corresponding bands of the treated nonoutgassed samples. Similar effects were observed on photoluminescence excitation of water samples. Two excitation bands monitored at 425 nm were observed at 272 nm and 330 nm. After EMT and/or outgassing, a decrease (> 60%) was observed in the intensity of these two bands. Altogether, these results indicate that electromagnetic treatment and/or outgassing decrease in a similar fashion the photoluminescence intensity in water samples. They also suggest that this effect is most likely indirectly attributed to the presence of gas bubbles in water. The possible role of hydrated ionic shell around the bubbles in the observed extraluminescence is discussed.

“…Measurements were not continued until dissipation completion time; this is of interest for continuing studies. However, Oshitani et al (1999) showed that the "memory effect" from the exposure of 10 cc of water to 0.4 T (4,000 G), which required about 20 min for a maximum effect, began to decay after 3 days and had disappeared by 5 days.…”

“…The stability in solute diffusion speed over the time measured suggests that either the magnitude of the intensity, the static property of the 1600 G field, or perhaps the duration (6 min vs 60 min) created the conditions for this effect. After a sufficient duration of exposure, which was longer than Oshitani et al's (1999) 20 min, the stored energy was maintained until it was dissipated. We have suggested that a process involved with the life time (10 -12 s) of the hydronium atom is involved.…”

SummaryDifferent volumes (25, 50, 100 cc) of spring water were exposed to either (160 mT, 1600 G) static magnetic fields, time-varying 7 Hz, 140 nT or 400 nT magnetic fields, or sham conditions for one hour. During the subsequent hours diffusion velocities for 6 µL aliquots of a solute (India ink) in 80 µL of water were then measured every 15 minutes. A sudden and protracted increase by a factor of two in diffusion velocity as a function of the exposed volume was conspicuous only for water treated by the static 1600 G magnetic field. The results are congruent with the quantified estimates of energy stored within water, the increased viscosity at the boundary of interfacial and bulk water as described by Del Giudice et al. (2010) and the dissipation of organization between hydronium atoms. This effect may lead to a simple, reliable experimental model to study "water memory".

“…It has been demonstrated in recent years that magnetic fields influence the physicochemical properties of water and aqueous solutions and suspensions [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Different hypotheses for the influence of magnetic fields on water and aqueous solutions have been extensively studied [25][26][27].…”

This work examined the removal of Pb(II) using a chitosan derivative (SB, synthesized from benzaldehyde) assisted by a magnetic field. The adsorption capacity for Pb(II) was investigated. It was found that 1) the pH and concentration of the ion solution, as well as exposure time and strength of magnetic field, affected the degree of adsorption; and 2) studies of the adsorption isotherms and kinetics of ions onto SB revealed that SB showed enhanced adsorption capacity towards Pb(II) ions in a magnetic field compared with magnetically untreated samples. The Langmuir and Freundlich isotherm were applied to describe the experimental adsorption, and the maximum adsorption capacity of SB for Pb(II) was 2.5040 mg/g, when assisted by a magnetic field of 480 kA/m.
