Abstract
Rate constants for the reactions of three commonly used organic buffers and hydroxyl radicals were measured using steady-state competition kinetics with thymine. For Hepes (4-(2-hydroxyethyl)-1-piperazine-ethanesulphonic acid), Tricine (N-[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]glycine and Tris (2-amino-2-hydroxymethylpropane-1,3-diol) the rate constants were 5.1×109, 1.6×109 and 1.1 × 109 1·mol-1·s-1, respectively.
