Comparative studies of ipe (Tabebuia spp.) wood photodegradation caused by treatment with acid and alkaline buffers. A study on photodegradation of ipe wood using xenon lamp and UV lamp light has been carried out. Colour of the samples was measured using a Datacolour 600 spectrophotometer prior to their soaking in acid and alkaline buffers, after soaking and successively after 1, 5, 10, 25, 50 and 100-hour irradiation. It was concluded that the treatment with acid and alkaline buffers causes opposite changes of the investigated colour coordinates. Samples after treatment with the acid buffer were lighter and yellower in colour, but less red, while after treatment with the alkaline buffer they were darker and redder, bur less yellow. Generally treatment with the alkaline buffer caused more significant changes of ipe wood in comparison to treatment with the acid buffer. Samples treated with the acid buffer were more prone to changes of colour (∆E*) due to light irradiation in comparison to the samples treated with the alkaline buffer. More significant changes of colour were observed in the case of UV irradiation in comparison to irradiation cause by xenon lamp light.
