Abstract

A screen-printed copper ion sensor with photocurable poly(n-butyl acrylate) (pBA) membrane based on ionophore o-xylylene bis(N,N-diisobutyldithiocarbamate) (o-xc) was successfully fabricated. Poly(2-hydroxylethyl methacrylate) (pHEMA)-modified Ag/AgCl screen-printed electrode was used in the development of the sensor and the sensor was characterized by potentiometric method. Optimization of pBA membrane for the electrode was carried out by varying the compositions of sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaTFPB) and o-xc to determine the best analytical performance. The addition of NaTFPB and the increment of its ratio relative to o-xc showed super-Nernstian, small linear range, and high detection limit. For sensor fabricated based on o-xc without the addition of NaTFPB, the sensor showed Nernstian response. The best optimized sensor showed Nernstian slope with 31.29 mV/decade over a wide linear range of 1.0 × 10-2 – 1.0 × 10-6 M and low detection limit of 1.89 × 10-7 M. The sensitivity of this sensor was also improved over the other copper ion sensors fabricated by similar photocuring technique. In addition, based on the separate solution method (SSM), this sensor exhibited good selectivity towards copper ion with low logarithm selectivity coefficient value for monovalent and divalent cations namely K+, Na+, Ca2+, Mg2+, Ni2+ and Co2+.
