Abstract: In order to remove fluorine from a zinc containing solution before zinc electro-refining in lower cost, fluorine is removed by adsorption from a zinc containing solution (leached solution) utilizing the character of the predetermined iron compound or zinc compound which can adsorb fluorine in an acid solution and desorb fluorine in an alkaline solution. The fluorine adsorbent/desorbent having adsorbed fluorine is treated in an alkaline solution, to desorb the fluorine. This makes it possible to regenerate the fluorine adsorbent/desorbent. Further, an electrolytic solution for zinc electro-refining can be prepared in lower cost, thus total zinc refining costs can be reduced.

Abstract: A fluorescence emitted by a measurement object at a measurement point is measured. When the fluorescence is measured, a measurement object is irradiated with laser light whose intensity is time-modulated by using a modulation signal at a predetermined frequency. Then, the fluorescence emitted by the measurement object is formed to a flux of the fluorescence having uniform distribution of light intensity, and a plurality of partial fluorescent signals are generated by receiving a plurality of divided portions of the flux of the fluorescence. At least some of the partial fluorescent signals are added altogether to generate a single fluorescent signal. Finally, a fluorescence relaxation time of the fluorescence emitted by the measurement object is calculated from the generated fluorescent signal by using the modulation signal. When fluorescence intensity of the fluorescence calculated from the fluorescent signal exceeds a predetermined threshold, the partial fluorescent signals to be added are limited in number.
