Here, an all-solid electrode, in-situ soil pH sensor is demonstrated, which mitigates many of the drawbacks associated with the traditional method of pH analysis. The soil pH sensor uses antimony as ...

In this study, pH sensors with ZnO nanorods (NRs) or film were fabricated by using a low-cost and simple hydrothermal method. A 100 nm ZnO film was deposited on a glass substrate via radio frequency ...

Analyzes of predicted pH from three independents experiments revealed high recoveries (95-103%) and low relative standard deviations. Thus, the PhotoMetrix app was viable for colorimetric pH ...
