Abstract

Wood reacted with either periodic acid or sodium periodate is resistant to attack by brown- and white-rot fungi and subterranean termites in laboratory tests. Both periodic acid and sodium periodate react with wood in 2 to 4 h in aqueous solutions at room temperature. After reaction, the chemicals are leach-resistant. Periodic acid-reacted wood, after leaching, has a threshold retention of 0.26% for Gloeophyllum trabeum and 0.11% for Coriolus versicolor. Higher threshold retentions are required for sodium periodate.
