Hlau sulfide yog cov tshuaj lom neeg uas yooj yim oxidizes hauv huab cua los tsim cov pa phem xws li sulfur dioxide. Nws kuj tuaj yeem ua rau muaj kev phom sij nrog lwm cov tshuaj. Yog li, hlau sulfide yuav tsum tsis txhob sib cuag nrog cov tshuaj hauv qab no:
1. Cov kua qaub: Thaum cov hlau sulfide tuaj yeem sib cuag nrog cov kua qaub xws li hydrochloric acid, nitric acid, thiab acetic acid, nws tsim cov pa phem uas tuaj yeem ua rau tawg thiab hluav taws tau yooj yim.
2. Oxidizing agents: Thaum cov hlau sulfide los rau hauv kev sib cuag nrog oxidizing agents (xws li poov tshuaj permanganate thiab hydrogen peroxide), nws reacts hnyav, tso tawm ntau heev ntawm tshav kub thiab tshuaj lom gases.
3. Tsis yog-cov khoom siv hlau: Thaum cov hlau sulfide los rau hauv cov khoom tsis yog-hlau (xws li chlorine, bromine, thiab iodine), nws kuj tsim cov pa roj carbon monoxide, uas tsim kev puas tsuaj rau tib neeg thiab ib puag ncig.
4. Qhov kub thiab txias: Hlau sulfide decomposes yooj yim ntawm qhov kub thiab txias, tso pa roj carbon monoxide thiab muaj peev xwm ua rau tawg thiab lwm yam tsis zoo.
