Kev siv thiab kev siv

Nws yog dav siv nyob rau hauv rodenticides, manufacturing cement, electroceramic cov ntaub ntawv, glazes, cib, frits, thiab enamels. Nws yog siv los ua ib txheej rau vuam electrodes thiab ua purifier nyob rau hauv cov txheej txheem glassmaking los xyuas kom meej uniformity thaum lub sij hawm purification ntawm iav melts thiab caustic soda brine. Cov khoom no kuj yog siv los ua qhov chaw tsim khoom ntawm lwm cov tshuaj barium xws li chlorides, peroxides, thiab nitrates.

Tsis tas li ntawd, BaCO3 / tin dioxide nanoparticles kuj muaj cov haujlwm photocatalytic thiab tuaj yeem siv rau degradation ntawm crystal violet dye, uas yog cov txheej txheem ruaj khov. Thaum qhov ntau npaum ntawm BaCO3 / tin dioxide nanoparticles yog 10 mg / 10 mL siv lead ua violet dye tov thiab UV- pom lub teeb irradiation lub sij hawm yog 8 h, crystal violet degradation tus nqi mus txog 92.1%; Thaum qhov ntau npaum ntawm BaCO3 / tin dioxide nanoparticles tau nce mus rau 20 mg / 10 mL siv lead ua violet dye tov, crystal violet degradation tus nqi nce mus rau 96.1%; cov hom nquag ntes photocatalytic kev sim pom tias qhov, hydroxyl radicals thiab superoxide ion radicals yog cov hom tseem ceeb.
