O mém projektu
Industrial tannin extract has a potential to become a new natural wood preservative agent. Conditions for acidic and enzymatic hydrolysis will be optimized to purify this extract from hydrolyzable tannins and others present impurities. Efficiency of selected conditions on final purity will be investigated and analyzed with common chromatographic and spectroscopic methods. These purified extracts will be applied on wood samples and their water and microbial resistance will be evaluated.
