Szajdak, Szczepański 2012: Impact of Solvent on the Elution Rates of Organic Matter From the Secondary Transformed Peat-Moorsh S
Theme III. Agricultural use of peat and peatlands
The rates of organic matter elution in soil samples from 4.5 km long transect of peatland located on secondary transformed organic soils (peat-moorsh soils) were investigated.
The rates of the elution process were calculated from the kinetics of the first order reaction model from the absorbance values. The absorbances of samples were monitored with UV-VIS spectrophotometer at four wavelengths λ=272 nm, 320 nm, 465 nm, and 665 nm.
All experiments were repeated in water and 0.5 M ammonium acetate buffer solution at different ionic strength μ=0.25, μ=0.40, μ=0.65.
