Webb21 feb. 2024 · Desulfurized gypsum (DG) as a soil modifier imparts it with bulk solid sulfite. The Fe(III)–sulfite process in the liquid phase has shown great potential for the rapid removal of As(III), but the performance and mechanism of this process using DG as a sulfite source in aqueous solution remains unclear. In this work, employing solid CaSO3 … WebbIt is known that a considerable amount of CO is adsorbed on the cobalt sites over cobalt-containing catalysts.10,11 O2 adsorption is thought to proceed in 2 consecutive steps on cobalt-ceria sites and CO2 formation takes place via 2 Langmuir-Hinshelwood surface reactions: one with the adsorbed CO on the noble metal12,13, and the other with the …
