Description

Application

• Research on the Synthesis of Zinc-Ammonium Phosphate Using Galvanic Waste Sludge as a Source of Zinc: This study explores a novel approach using hydrochloric acid solution in the synthesis process aimed at valorizing waste materials. The article demonstrates a chemical strategy that enhances resource recovery, significantly contributing to waste minimization in industrial practices (Morgovan et al., 2024).


• Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas: The study integrates hydrochloric acid solutions in the development of a novel, cost-effective contactless conductivity sensor. This sensor uses a simple paper-based system for the in-situ monitoring of gases, providing a significant tool in environmental monitoring and analysis (Nacapricha et al., 2020).
