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. Copyright © by Walter de Gruyter.
