Described is a wood composition and a method for its preparation by treating wood with a first aqueous solution comprising one or more lanthanide derivatives, optionally rinsing with water and finally treating the wood with a second aqueous solution comprising one or more bases or one or more acid salts thereby precipitating a water-insoluble lanthanide complex within the wood. In addition, the method may be practiced by reversing the order of the treatment steps.

A method of preserving wood or wood-derived matrices comprising the steps of: (a) contacting the wood or wood-derived matrices with a first aqueous solution comprising a lanthanide derivative to impregnate the wood or wood-derived matrices with the lanthanide derivative; and (b) contacting the wood

A method of preserving wood or wood-derived matrices comprising the steps of: (a) contacting the wood or wood-derived matrices with a first aqueous solution comprising a lanthanide derivative to impregnate the wood or wood-derived matrices with the lanthanide derivative; and (b) contacting the wood or wood-derived matrices with a composition comprising a second aqueous solution comprising a compound reactive with the lanthanide derivative or derivatives of step (a) to impregnate the wood or wood-derived matrices with the reactive compound and produce a water-insoluble lanthanide complex impregnated in the wood or wood-derived matrices.
