Investigation of Leaching Performance of Wood Materials Colored with Walnut Husk

Abstract

The purpose of this study to develop an eco-friendly wood stain alternative to synthetic dyes and to determine the desorption on wood surfaces. For this purpose; wood blocks was prepared from Turkish oriental beech (Fagus orientalis Lipsky), Scots pine (Pinus sylvestris L.), oak (Quercus petraea spp), and walnut (Juglons regia L.). Plant dyestuff was extracted from the Walnut husk by using ultrasonic assisted method. For mordants, ferrous sulfate (Fe₂(SO₄)₃.7H₂O), aluminum sulfate (KAl₂(SO₄)₃.18H₂O), copper sulfate (CuSO₂.5H₂O), and vinegar (CH₃COOH) were chosen and applied to wood blocks with immersion (classic) and immersion+ultrasonic assisted methods. To determine the stability of paint, the effect of such parameters as the medium pH (5, 7 and 9), temperature (22 and 40 °C), agitating speed (10 and 30 rpm) in leaching test was studied. Result showed that, generally aluminum sulfate and ferrous sulfate performed well desorption were reduced the desorption on all wood species surfaces.
