Abstract

Phosphorus in nature is very important both in water and in soil. The form of the compound phosphate has become an important study in agriculture and the environment. Potentiometry is a recommended effective method to measure or monitor ion phosphate’s concentration in nature compared to the spectrometric method, as supporting information for further purposes. However, the problem is the unavailability of suitable sensors or those are rarely found. Thus, this study reports the development of electrodes made from cobalt as an active part in the potentiometric detection of phosphate ions. Cobalt was immobilized electrochemically on the surface of carbon rods using cyclic (CV) and linear sweep (LSV) voltammetry methods in a potential range from 0 mV to −1000 mV. The amount of cobalt deposited was measured spectrometrically, and the morphology of the cobalt-carbon electrode is captured by SEM. The amount of electrodeposited cobalt was higher in LSV-based electrodes than in CV-based electrodes. Consequently, the electrode performance tested by the potentiometry method showed that LSV-based has better performance (linear region, sensitivity, and reproducibility) than CV-based electrodes.
