Determination of calcium ion in sap using carbon nanotube-based ion-selective electrodes
A new reduced-size solid-state electrode using carbon nanotubes as the transducing layer has been developed for the direct determination of Ca 2+ in sap, overcoming problems encountered by commercial ISEs analysing real complex samples. We show that this solid-contact ISE, which can be easily miniat...

| description | A new reduced-size solid-state electrode using carbon nanotubes as the transducing layer has been developed for the direct determination of Ca
2+
in sap, overcoming problems encountered by commercial ISEs analysing real complex samples. We show that this solid-contact ISE, which can be easily miniaturized, can be used directly in diluted real samples without any other pretreatment. The performance parameters of the new ISE include a Nernstian slope and excellent stability, good coefficients of selectivity, range of linearity (10
−5
to 10
−2.5
M) and limit of detection (10
−6.2
M), thus making it an excellent tool for determining Ca
2+
in a wide range of plant species.
A new solid contact ion-selective electrode for the detection of calcium in real sap samples is presented with very good short and long term stability and with short response times. |
