- •
B–S–I performs much better than B–I in Hg0 removal under the same conditions.
- •
KI can be oxidized to I2 by air and starch–iodine complex can be formed on B–S–I.
- •
Starch–iodine complex can provide I2 for Hg0 to form iodated mercuric compounds.
- •
O2 promotes Hg0 removal and B–S–I shows a higher extent of Hg0 removal than B–I.
- •
SO2 shows distinct effects on B–S–I and B–I, and mainly shows promotable for B–S–I.
