This research explores using natural sulphurous waters for various chemical applications. It focuses on precipitating heavy metal ions, eliminating free radicals, and recovering sulphur. Key findings include successful H₂S detection, and sulphur recovery through oxidation with hydrogen peroxide. H₂S effectively precipitated several heavy metals (except chromium) and neutralized free radicals. The study demonstrates that sulphurous water is valuable for chemical reductions, metal precipitation, organic synthesis, and radical scavenging, suggesting it could be a sustainable source for sulphur recovery, reducing reliance on less healthy extraction methods.
