内容記述タイプ Abstract
内容記述 Due to falling snow along the coast of the Japan Sea, relatively larger amount of ions such as chloride, sodium, magnesium ions are adsorbed on the snow, if compared with the other ions, i.e., sulfate, nitrate ions. The similar adsorption phenomena can be observed for ice crystal in water containing several ions. In this study, adsorption of phosphate and ammonium ions on ice crystals was examined experimentally by keeping spherical ice crystals in the solution prepared with phosphate and ammonium salts, they were chosen as pollutant substances occurring the eutrophication of lake water. At adsorption of the ions on ice crystals, it was able to discriminate a comparatively large selectivity between phosphate and ammonium ions. This phenomena was a physical adsorption with the influence of hydrogen bonds on the ice surface. This adsorption was a Langmuir-adsorption type. Adsorption capacity was existed at the range of 0.2-0.6℃, and the adsorption amount at about 0.2 min was found to be larger than that observed after 0.2 min. It should be noted that temperature plays an important role to deal with ice crystals functioning as usual adsorbents. Besides, recovery of the ions was comparatively easier than usual adsorbents because dissolution-water on early stage of ice crystals that adsorbed the ions had higher concentration of the ions than the dissolution-water on later stage. It is expected that adsorption of phosphate and ammonium ions on ice crystals plays an important role for the purity of water pollution in ponds, lakes, swamps, and so on.
