A spectrofluorimetric study of the extraction of mercury with 1,2-dichloroethane as an ion-pair formed between the cryptand 2.2.1-mercury complex and the eosinate counter-ion is described. The detection limit for mercury is 0.7 ng/ml, and the linear working range up to 125 ng/ml of mercury. The relative standard deviation is found to be 2.0% at the 100 ng/ml level. The proposed method has been tested for the determination of mercury in coal. 12 refs., 2 figs., 2 tabs.
