Summary
Chemicals used for protection of wood against fungi may be released in water when the sample comes into contact with water. The process of release of pentachlorophenol in water was studied in this paper, when the presaturated wood specimen is immersed in a finite volume of water up to a time at which equilibrium is not attained. The wood sample is then dried and immersed again in water. This process is continued many times. Moreover a finite coefficient of matter transfer at the wood surface is observed. A numerical model with finite differences was successfully tested by comparing the kinetics of release obtained either by experiments and calculation. The process was simplified in the sense that only the transfer of the chemical through the water located in the wood was considered. The model is thus able to provide the kinetics of release and the profiles of concentration.
