Determination of boron given to wood calculated by some expression types

Abstract

In this study, boron amount of in wood given by impregnation was evaluated as based on oven dried weight of wood, solution uptake of treatment and actual boron detected by ion chromatograph in order to make a base for further evaluations. Wood specimens were prepared from Japanese cedar (Cryptomeria,japonica Don.) and impregnated as three concentration levels of boric acid 0.25, 1.00, and 4.70 % aqueous solutions. Boron given to wood was calculated by different types of the expressions.
