英文摘要A paper-based ion-selective electrode system for determination of Ca~(2+) in seawaterwas described in the paper. The electrode system was constructed on a paper chip, composed of an all-solid-state polymeric membrane indicator electrode consisting of conductive carbon inks coated by a Ca~(2+)-selective membrane and an all-solid-state reference electrode consisting of Ag/AgCl inks coated by a lipophilic salt-incorporating polymeric membrane.The content of ionophore and the thickness of the ion-selective membrane were optimized, and the stability of the reference electrode and the selectivity of the electrode were investigated. The results indicated that the electrode system showed a stable potential response with a slope of 24.3 mV/dec in the linear range from 1.0×10~(-4) to 3×10~(-2) mol/L under the background solution of 0.5 mol/L NaCl. The practical application of the proposed sensor system was carried out for detection of Ca~(2+) in seawater samples, and the results agreed with those by inductively coupled plasma-atomic emission spectrometry.
