Yukihiro KON- DOH, Masamitsu KATAOKA and Tomihito KAMBARA (Department of Chemistry, Faculty of Science, Hokkaido University, Kita 10, Nishi 8, Kita-ku, Sapporo-shi, Hokkaido) A fluorometric micro determination of zinc by using 8-quinolinol-5-sulfonic acid (H_2QS) was described. The reagent reacts with zinc (II) to produce chelate anion. In the presence of trioctylmethyl- ammonium chloride (Gapriquat) a ternary complex is formed, which is easily extracted into chloroform phase. The extract has the excitation and emission maximum at 400 nm and 522 nm, respectively. Fluorescence intensity is constant over the pH range from 7.7 to 8.2, where the observed blank value is very low. The recommended procedure is as follows. To a sample solution containing (5.0〜 250.0) nmol of zinc (II) are added 7 ml of 1 mM H_2QS solution and 10.0 ml of borate buffer (pH 8.0). The solution is diluted to 50 ml with water and shaken with 10.0 ml of 7 mM Capriquat-chloroform solution for 5 min and then allowed to stand for 30 min. The organic layer is transferred into a beaker containing anhydrous sodium sulfate to remove remaining water. Then, the fluorescence intensity of the extract is measured by means of a Shimadzu digital spectrofluoro- photometer RF-510. The calibration curve showed a good proportionality in the concentration range from 5.0 nmol to 150.0 nmol. The effects of diverse ions on the determination of zinc were studied. In the determination of 70 nmol of zinc, twice molar amounts of cobalt (II) and nickel (II) gave negative errors, whereas twice amounts of cadmium (II) and aluminum (III) gave positive errors. One can eliminate the interference due to aluminum (III) by the addition of tiron.
