The compound was tested for the fabrication of a potentiometric sensor for Hg2+ metal ions. The sensor based on photocurable self-plasticizing poly(n-butylacrylate) membrane with immobilized BTCH as ionophore exhibits linear response in a Nernstian manner within the concentration range of 10(-5) - 0.1 M mercury ions. The sensor displays low detection limit with response time between 50 - 100 seconds. The electrode reveals a good selectivity for mercury ion over several other tested cations.
