Kinetics of Thiocyanate Formation by Reaction of Cyanide and Its Iron Complexes with Thiosulfate

Acidity of persulfides and its modulation by the protein environments in sulfide quinone oxidoreductase and thiosulfate sulfurtransferase

“…1 B , reaction f ), which involves the rate constant of the reaction between the persulfidated enzyme and cyanide, k cat / K m cyanide . The spontaneous reaction between the substrates at different pH was found to be negligible under our conditions, in accordance with reported data ( 36 ). A sigmoidal increase in activity with pH was observed, with an apparent p K a of 8.47 ± 0.06 and a maximum apparent rate constant of (4.0 ± 0.1) × 10 5 M −1 s −1 at alkaline pH ( Fig.…”

Study on Removal Mechanism for Copper Cyanide Complex Ions in Water: Ion Species Differences and Evolution Process

“…Chen et al [ 32 ] found that Ir, Pd, and Pt form complexes with cyanides and determined the structures of the related complexes through characterization methods. Kurashova et al [ 33 ] found that cyanides form related complexes with Fe 3+ and studied the reaction kinetics of Fe 3+ forming complexes with cyanides. Andrews et al [ 34 ] discovered that Zn, Ge, and Hg react with cyanides to form complexes and determined the related structures of cyanide complexes and isocyanide complexes through experimental characterization.…”
