Possible method of aluminium speciation in forest soils

Popis výsledku v původním jazyce

Labile Al forms and species can be a threat in acid soils due to their potential toxicity to plants. However, there is no universally accepted extraction method. Several extraction reagents for Al release from soil have been tested. KCl (0.5 or 1 M) is recommended for extraction of exchangeable Al, while 0.5 or 0.3 M CuCl2 is suggested for extraction of `weakly organically bound Al'. Both 0.1 and 0.05 M Na4P2O7 are shown to be suitable for the extraction of `total organically bound Al'. These extraction s are relatively simple, robust, and applicable to different soils and soil horizons. In the second part of the paper, detailed speciation of exchangeable soil Al by means of an HPLC instrument equipped with an ion column (IC) is presented. An experiment al set-up is described and tested on a set of samples. Interpretation of the speciation results is proposed, based on the separation of Al ions and Al complexes according to their charge. Speciation is shown to be dependent mainly on s
