“…The log[(A s -A 0 )/(A max -A s )] was plotted versus log of the concentration of the respective metal ion to determine the binding constant and the stoichiometry of binding as reported 33 . This could not be done for AM1 as there was no signi cant change in its UV/Vis spectrum upon interaction with Hg 2+ .…”

Mercury (Hg) causes serious health issues in its all forms. De ciency as well as excess of copper ion (Cu 2+ ) in human body is hazardous. A series of four compounds have been derived from carboxylated benzoic acids (benzoic acid, isophthalic acid, terephthalic acid and phthalic acid) and 4H-1,2,4 triazole-4amine and characterized. Fluorescencce detection of Hg 2+ was recorded by the derivates with benzoic acid and isophthalic acid while the derivatives of terephthalic acid and phthalic acid detect Cu 2+ by uorescence "off" mode. Metal ions like
