Application of cement as new electrode material and solid-phase microextraction material demonstrated by...

Because of its unique pore network, good strength, and low cost, cement was used as a new electrode material and solid-phase microextraction (SPME) material for the first time. It was mixed with carbon to make a new electrode, cement carbon electrode (CCE). The as-prepared CCE was used to demonstrate the application of cement in SPME by Ru(bpy)(3)(2+) electrochemiluminescent detection of perphenazine (PPZ). The calibration plot for PPZ is linear from 1.0 × 10(-9) to 3.0 × 10(-6)M with a detection limit of 3.1 × 10(-10)M. The method was successfully applied to the detection of PPZ in urine sample. Cement-based electrode material may also find broad applications in electrochemistry industry, such as electrochemical wastewater treatment.
