Abstract

Rate coefficients were measured for gas-phase electron-ion recombination of H3O+ and for ion-ion recombination of H3O+ with Cl-, Br- and I- in five H-2-O-2-N-2 flames spanning a temperature range 1820-2400 K. A novel, simpleand accurate technique was employed involving total positive ion collection at an electrode located a variable distance downstream of the flame reaction zone; a bias voltage was applied between the collection electrode and the metallic burner. The measured values of the recombination coefficients in cm(3) molecule(-1) s(-1) units are: (0.0132 +/- 0.0004)T-1.37+/-0.05 for H3O+/e(-); (20.8 +/- 0.7)T-2.52+/-0.16 for H3O+/Cl-; (1.01 +/- 0.04)T-2.14+/-0.07 for H3O+/Br-; and (8.82 +/- 0.35)T-2.40+/-0.12 for H3O+/I-.
