Preparation of acetoacetylated wood meal and its properties. Part 2. Copper ion fixation by acetoacetylation

Keywords: acetoacetylation, chemical modification, copper, diketene, ?-ketoester, leaching test

Fixation of copper ions to acetoacetylated wood meal (AAWM) was conducted in Cu(OAc)₂-MeOH solution. The maximum amount of copper fixed to AAWM was 147.9 mg g^?1 under optimum conditions. From FT-IR analyses of AAWM containing copper ions (AAWM-Cu), it was concluded that a chelate was formed between copper and the acetoacetyl group of AAWM. In a leaching test, half of the copper in AAWM-Cu was retained, even at pH 4.0.
