Abstract A specific and very sensitive optical chemical sensor (optode) for mercury ion
sensing has been developed. The optode was prepared using ETH–5294 as a
chromoionophore and the recently synthesized ionophore, 7-[(2-methyl-1H-indol-3-yl)
methyl]-5, 6, 7, 8, 9, 10-hexahydro-2H-1, 13, 4, 7, 10-benzodioxatriaza cyclopenta-decine-3,
11 (4H, 12H)-dione. Interacting the mercury ions and the membrane phase, Hg 2+–
ionophore complex forms and causes a change in the absorbance of the sensor. The ...
