Methods for the analysis of boron in wood were reviewed and one, a method in which base titration of a mannitol/boron complex is done, was chosen for possible routine use. Method parameters were tested and the stages were modified to arrive at a routine which can determine boron content in wood within 5% accuracy. Hot water leaching of chip samples, 2.54 x 2.54 cm x 2 to 3 mm thick, of wood which has been given borate/antisapstain treatment is better than 95% efficient within four hours; this is as efficient as a ten-cycle extraction on a soxhlet apparatus. Using an automatic titrator, analysis for boron is done by titrating a mannitol complex of the boron in the extract. The simplicity, low expense, speed, and accuracy of this routine give it the advantage over several other methods. The aqueous extracts of wood, the mannitol reagent, and secondary components of boron treating formulations can all add to the apparent boron content of the wood sample; these factors are variable but generally total about 8 *g boric acid equivalent per cm2 of wood surface. The method is also suitable for the analysis of boron in heavily (preservative) treated wood.
