The Structure of Water Induced by Specific Ceramics Treatment and Effects of Treated Water in View of Some Biological Aspects

Abstract

The structure of water induced by a high-temperature sintered kaolinite ceramics treatment was studied in view of thermally stimulated depolarized current (J) and temperature profiles (TSDC analysis) on the iced treated water and 1H-Nuclear Magnetic Resonance (NMR) spectrometry on the treated water as well as some physical properties of the sintered ceramics. In addition, some biological effects of the treated water were examined to give indirect evidences for the proposed water structure. The treated water were positively charged based on essentially the formation of electric double layer interface between the ceramics surface and water flow, without any absorption-desorption phenomena to substances contained in water to be treated by the ceramics. The positive charge was indirectly affirmed by TSDC and 1H-NMR analyses on ionexchanged water and for the drinking water. The water structure derived by the existence of chlorine substances was apparently disappeared from 1H-NMR spectrum, probably by the apparent neutralization or accumulation of chlorine substances through interaction with positive charge. This phenomenon seemed to be closely related with the fact that absorption of chlorine ion through a vegetable root was greatly depressed when the treated water by the ceramics was used. The treated water was also proved to restrict the growth of E. coli in poor nutritional culture media and the production of bacterial cellulose by CFJ-002 (New bacterium cellulose-producing microorganism, an enterobacter) stock, and to suppress the oxidation action of hydrogen peroxide.
