Reaction of Long-Chain Iodoalkanes with Gold Surfaces

Silver-functionalized silica aerogel: towards an understanding of aging on iodine sorption performance

“…Given TEM evidence for Ag 0 nanoparticles, it is plausible that the Ag-S-r species (where S is the thiol functional group and r is the organic chain tethered to SiO 2 ) records Ag atoms at the surface of the Ag 0 particles that interact with thiol groups. The component at 369.1 eV is consistent with an Ag-organic species 33,34 and may represent Ag ions trapped in the organic matrix. Alternatively, given the strong dependence of Ag3d binding energy on the size of silver nano-particles, where smaller size yields higher Ag3d BEs, 35 results suggest that there is a reservoir of Ag 0 particles/ clusters at <2 nm that could grade into individual Ag atoms/ ions.…”

Bromine pretreated chitosan for adsorption of lead (II) from water

“…The maximum adsorption capacity of 0•81 mg/g were reached in sorbent's dose range of 15-20 g/L that further decreases with increasing sorbent dose as may be due to specific surface adsorption phenomenon. At low sorbent dose all the active sites of sorbent get utilized completely and effectively resulting in high lead adsorption capacity, on the contrary increasing sorbent dose while maintaining lead concentration steady escorts to surplus of adsorbent sites (Hirayama et al 1998;Meghat Hanafiah et al 2007). 3.5d Effect of initial lead concentration: The amount of lead (II) distribution amongst sorbent and solution at equilibrium is vital in determining maximum lead adsorption capacity of adsorbent.…”
