COUMARIN DERIVATIVES HAVING HG(II) ION SELECTIVITY, METHOD FOR PREPARING THEREFOR, DETECTING METHOD USING THE SAME

摘要

PURPOSE: A coumarin derivative with bivalent mercury ion selectivity is provided to ensure high solubility and high fluorescence intensity in low bivalent mercury ion concentration. CONSTITUTION: A coumarin derivative has a bivalent ion selectivity and is denoted by chemical formula 1. The coumarin derivative of chemical formula 1 is prepared by reacting a compound of chemical formula 2 with 1,2-ethandithiol according to reaction formula 1. The bivalent mercury ion is selectively detected using coumarin derivative of chemical formula 1. The detection of the bivalent mercury ion is performed by measuring UV ray absorbance of the coumarin derivative.
