실험 절차

In 300 ml of purified water, 1.64 g of sodium hydroxide was dissolved. In the resultant aqueous solution, 6.06 g of cinnamic acid (purity 99.9%, conjugate number 4) was thoroughly dissolved under stirring, to produce a sodium cinnamate aqueous solution. The pH value of this aqueous solution was adjusted to 11.0 with a 0.1N sodium hydroxide aqueous solution. Then, a europium chloride aqueous solution obtained in advance by thoroughly dissolving 5.0 g of europium chloride (EuCl3.6H2O; purity 99.99%) in 100 ml of purified water was gradually added with stirring into the aforementioned sodium cinnamate aqueous solution at room temperature. Consequently, a white salt of europium cinnamate, [(C6H5CH=CHCOO)3Eu], was obtained in the form of a precipitate. Subsequently, the reaction solution was adjusted to pH 5.0 with 0.1N hydrochloric acid and then thoroughly stirred. The europium cinnamate thus produced was separated by means of a glass filter, thoroughly washed with 500 ml of purified water and dried in vacuo at 80° to 100° C. for 20 to 24 hours.
