抄録
From the viewpoint of the phytotoxicity and mobility of Al3+ released from soil minerals due to soil acidification, the interaction between Al3+ and acrylic acid (AA) and polyacrylic acid (PAA) as a model compound of fulvic acid was investigated. The interaction was examined at pH 3 so as to avoid the hydrolysis of Al3+. The interaction between Al3+ and AA was weak. However, the interaction between Al3+ and PAA was strong and depended on the initial (COOH in PAA)/Al molar ratio (RP) of the solution. For the range of 1/RP, the interaction between Al3+ and PAA can be divided into three categories: (1) 1:1 Al-PAA-complex (an Al3+ combines to a carboxyl group), (2) intermolecular Al-PAA-complex (an Al3+ combines to more than 2 carboxyl groups of other Al-PAA-complexes) in addition to the 1:1 Al-PAA-complex and (3) precipitation of intermolecular complexes. In conclusion, RP is an important factor affecting the behavior of Al3+ in acidic soil solution.
