Bio-Precipitation of Zn (II) from Municipal Wastewater Spiked with Zinc

Phosphorus (P) is ubiquitous in the environment, but its measurement is costly and time‐consuming. Sensor‐based measurement shows potential, but selection of right metal remains the major challenge due to strong P species dependence on pH. This study examined the feasibility of pure cobalt, molybdenum, and their electrodeposited alloy, Co63Mo42 (wt %), as phosphate sensors. The cobalt, molybdenum and alloy exhibited mixed potential, Nernst potential, and oxidation‐reduction (red‐ox) mechanisms, respectively. Alloy showed good selectivity over a wide pH range, but high limit of detection and long response time (8–14 minutes). Yet, alloy provides a new opportunity for improving electrochemical phosphate sensors.
