摘要:

The florescent characteristics of the complex formed by 1, 5-dihydroxyanthraquinone with Mg(II) in aqueous ethanol (λex490 nm,λem=600 nm; pHap=9.1-9.6; 10% H2O; reagent concentration=4×10−5M) are described. The stoichiometry and the stability constant (1:1 and log K=4.90) are determined. A new fluorometric method for the determination of 10-100 ppb Mg(II) is proposed.
