Abstract

Combined treatment effect of the chromic acid and acetylation was studied on dimensional stability, chromium leaching, water absorption and extractive leaching in Populus deltoides Bartr., Celtis australis Linn. and Bombax ceiba Linn. In acetylation followed by chromic acid application lower values of chromium pick up and the higher amount of hexavalent chromium leaching was observed. Chromic acid treatment followed by acetylation showed best results. No hexavalent chromium leaching was observed in this case. The water repellent effectiveness (WRE) values after 136 hrs., immersion in water was 41.04%, 51.44% and 44.95% in P. deltoides, C. australis and B. ceiba, respectively. The corresponding reduction in water absorptivity (RWA) values was 29.68%, 32.82% and 30.94%, respectively. This treatment also reduced extractive leaching.
