有機物分解に対するオゾンウルトラファインバブル混合の効果.

Because of investigating effect of mixed ultra-fine ozone-rich bubble (UFORB) liquids on the degradation of organic compounds, we observed molar concentration of aqueous solutions of methylene blue (organic compound model) against elapsed time by using UFORB or ozone-water (OW) suspended in ultrapure water (UPW) or tap-water (TAP). Excellently lower concentration of methylene blue by using UFORB exhibited. Compared with that of OW, effect of both high decomposing ability and short processing time was excellently obtained. For discussing the experimental results, additional two experiments were conducted. Dissolved ozone-concentration of UFORB suspended in UPW or TAP was measured. For case of UFORB, highly ozoneconcentration in ultrapure water exhibited and was independence of elapsed time. However, that in tap-water decreased against elapsed time within the experimental errors. Relationship between number density and particle diameter of ultra-fine bubble was measured. Peak diameter of UFORBTAP was smaller than that of UFORB-UPW in relatively initial times. Moreover, differences between stability of ultra-fine bubble and ozone-concentration suspended in UPW or TAP was discussed. [ABSTRACT FROM AUTHOR]
