Abstract
Fick's diffusion equations have been solved for the Haxo and Blinks electrochemical determination of photosynthetic O(2) evolution. The model shows the method to be quantitative in the case of a "long" chamber measuring constant rates of O(2) evolution. Transients are amplitude distorted by an amount depending on the space distribution of the O(2) sources. A correction equation applied to the raw data permits the recovery of the original signal.
