文摘
- •
Pyrolysis evaporation results in the invalidation of Cl-containing active constituents in municipal waste.
- •
Sulfide serves as chemisorption site oxidizing Hg0 into HgS for char derived from tire waste.
- •
Both physical activation and chemical modification possibly remove or cover inherent active sites of char.
- •
The results provide a meaningful guidance on preparation method of low-cost mercury sorbent.
