Abstract:
This study successfully synthesized a composite material, CoPc@ISM/CNT, using dichlorophosphorus tetraphenylporphyrin chloride (PCl2TPP) as an ion-selective carrier, with the addition of cobalt phthalocyanine (CoPc) and carbon nanotubes (CNT). This composite material exhibited high sensitivity and selectivity toward perchlorate, with a linear detection range of 4.5×10-7 mol/L to 0.1 mol/L and a detection limit of 0.3 μmol/L. The addition of CoPc enhanced the detection of perchlorate, while CNT significantly improved the current response. By further designing a composite electrode and integrating it with quantitative analysis software, a portable perchlorate sensor was developed. Tests on real water samples demonstrated that the sensor achieved recovery rates between 98.5% and 106.9%, enabling on-site monitoring of perchlorate in water.
