Abstract
The kinetics of the reaction of absorbed hydrogen sulfide in an alkaline solution of sodium vanadate (NaVO/sub 3/) and the sodium salt of anthraquinone-2,7-disulfonic acid (ADA) were determined in a Durrum-110 Stopped-Flow Spectrophotometer. The reaction was first order in hydrogen sulfide and the rate constant was 9100/sec mole, assuming a first-order dependence on vanadium(V) concentration and zero-order dependence on ADA concentration. These results suggested that the Stretford reaction is faster than the absorption of hydrogen sulfide into the solution. Problems involved in measuring very rapid reaction rates are discussed.
