애플리케이션
- Speciation of tin ions in oxide glass containing iron oxide through solvent extraction and inductively coupled plasma atomic emission spectrometry after the decomposition utilizing ascorbic acid: This research employs hydrochloric acid as a critical component in the dissolution process, facilitating advanced analytical techniques for material analysis. The study is pivotal for developing new methodologies in the recycling and efficient use of materials (Saijo et al., 2022).
- Simple Preparation of Carbon Dots and Application in Cephalosporin Detection: Highlighting the use of hydrochloric acid in synthesizing carbon dots for cephalosporin detection, this paper introduces a novel approach to enhancing the sensitivity and specificity of antibiotic detection in complex samples, proving essential for both environmental monitoring and pharmaceutical compliance (Li et al., 2021).
- Assessing the behaviour of heavy metals in abandoned phosphogypsum deposits combining electrical resistivity tomography and multivariate analysis: This study utilizes hydrochloric acid in geochemical assays to assess pollutant distribution and mobility. It offers significant insights into environmental safety and pollution control strategies, particularly in the management of industrial waste residues (Vásconez-Maza et al., 2021).
- Fructan from Polygonatum cyrtonema Hua as an eco-friendly corrosion inhibitor for mild steel in HCl media: This investigation explores the use of natural fructan in the presence of hydrochloric acid to inhibit corrosion, providing an environmentally friendly alternative to traditional corrosion inhibitors. Such studies are crucial for sustainable industrial practices (Zhang et al., 2020).
- Monitoring the extraction of copper from chicken dung leachate using an aluminium electrode as an indicator: Hydrochloric acid plays a vital role in this novel electrochemical method to monitor copper levels in agricultural waste products, showcasing its importance in agricultural waste management and resource recovery (Kugeria et al., 2019).
