Description:
Tetra sulfide silane coated iron-copper nano-particle aggregates are found to be potentially very high capacity sorbents for vapor phase mercury capture. High equilibrium capacities were obtained for the silane coated iron copper nano-aggregate sorbent at 70 oC and 120 oC. Even at 120 oC, the equilibrium capacity ranged between 3 and 23 mg/g depending on the particle composition. Sorption runs were carried out by varying the copper content (~20 wt% to 0.5 wt%) for these sorbents while keeping the sulfur content constant at 6 wt%. Results indicate that the amount of copper can be kept minimal (~0.5 wt%) without effecting the capacity.
