The amounts of Mn, Pe and Al in H2O2 and NaOCl extracts during pretreatment of the soil for organic matter removal were determined. In addition acid ammonium oxalate extractable Mn, Fe and Al as well as amorphous aluminosilicates using boiling 0.5N NaOH procedure were determined on the residues. It was found that the oxides removed by NaOCl pretreatment were significantly lower than the amounts removed by H2O2 procedure. In the residue, Mn and Pe extractable by oxalate were less in the NaOcl treated soils than in those of H2O2. But in the case of amorphous aluminosilicates the result indicate that these soil constituents were more destroyed by NaOCl than H2O2- pretreatment. Therefore it was concluded that in specific mineralogical studies where the contents of amorphous aluminosilicates are desired the use of NaOCl for organic matter destruction should be avoided. |
