Time-resolved investigation of early processes in the reduction of Ag+ on polyacrylate in aqueous solution

Article Abstract:

Research was conducted to examine the early processes in the reduction of Ag+ on polyacrylate in aqueous solution. Pulse radiolysis experiments reveal that several steps ranging from microseconds to seconds are critical in building up a colored complex. Results demonstrate how strongly the elementary processes in the growth of small particles are affected by a polymer. It is, therefore, interesting to compare the very early steps with those taking place in the reduction of Ag+ in the absence of the polyanion.

Oxyhalogen-sulfur chemistry: kinetics and mechanism of the formation of bromamines from the reaction between acidic bromate and aminomethanesulfonic acid

Article Abstract:

Research was conducted to examine the kinetics and mechanism of the formation of bromamines from the reaction between aminomethanesulfonic acid and acidic bromate in strongly acidic media. The reaction was observed to be extremely slow and is completed only after about 600 min at pH 0.0. An 11-step mechanism, which allows the examination of other species in the reaction medium, is recommended.
