Abstract Scope |
Phosphate is known to play many key roles in human metabolism and plant growth. Although, its uncontrolled level may cause severe environmental and health issues. In order to avoid the problems associated with phosphate, its determination has got attention. Various approaches were developed for phosphate determination, among which electrochemical methods have shown to provide fast, simple and in-field measurement. Over the years, cobalt-based solid-state phosphate sensing electrodes were developed as potentiometric sensors. Many efforts have been made to replace cobalt with other materials to overcome its disadvantages such as high cost, low-selectivity and toxicity. Here we introduce a nickel-based solid-state electrode prepared by anodic electrodeposition of nickel oxide on printed carbon (Ni-PrC). The electrode characterized by FE-SEM, EDS and tested for potentiometric phosphate detection yielding a fast and linear response of -78.48 mV/decade within a concentration range of 10-6-10-1 M with high stability, reusability and phosphate selectivity. |
