内容記述 | Dilute volatile acidic aqueous solution was frozen by various freezing methods, and concentrations of solutes and pH of the sample were measured after the sample was completely thawed. Concentration of the volatile acid anion in the sample decreased, and pH of the sample increased after freezing. The decrease of solutes in the sample was almost equal to that detected in the gas phase. When dilute salt solution was frozen, solutes were excluded from ice and concentrated into the unfrozen solution. Concentrated anion combines with concentrated proton to form volatile acid such as acetic, formic or nitrous acid without reaction with any other chemicals. These volatile acids are saturated, and evaporation to the gas phase occurs. It is considered that the decrease in concentration of various solutes is mainly due to the freeze-concentration effect. | |||||
