| 内容記述 | The volumetric mass transfer coefficient, k(La), and the fractional gas holdup, ε(G), were measured by blowing a mixed gas of N2 and O2 at higher bubble frequencies from an upward vertical nozzle into the aqueous solution. And the saturation concentrations of dissolved oxygen in the solution containing SO4(2-) ion or Fe(Ⅲ) precipitate were also measured. The experimental results are summarized as follows. (1) The value of k (La) was not affected by pH of the solution and by ZnSO4, Na2SO4 or Fe(Ⅲ) precipitate contained in the solution. But the value of k(La) increased with temperature and the Reynolds number of gas flow at the orifice, Re(N). The activation energy of k(La) was 15kJ-mol(-1). (2) The value of ε(G) obtained in this work was in good agreement with those obtained previous works. And it is reasonable to assume the relationship between ε(G) and k(La) as valid by the comparison with those obtained previous works. (3) The saturation concentration of dissolved oxygen decreased with the concentration of NaCl and these values were in good agreement with those shown in JIS. And the concentration also decreased with the concentration of Na2SO4 in the solution, but was not affected by Fe(Ⅲ) precipitate. | |||||||
