Analysis of adsorption of heavy metals from water solutions by wood of selected domestic species
using X-Ray Fluorescence (XRF).The aim of this study was to analyze the absorption of three specific heavy
metals from model water solution by wood species from domestic Polish forests. This paper focuses on XRF
method to determine metal content in samples. European aspen (Populus tremula L.) and Black locust (Robinia
pseudoacacia L.) have been chosen. Firstly, shavings were prepared and soaked with standard solutions of lead
(II) nitrate, cadmium nitrate and mercury (II) chloride for 7 days. Then, the material was dried and reduced to
ashes using muffle furnace. Finally, content of absorbed metal was marked (XRF) and analyzed with a view to
initial contents of metal ions in standard solutions. It was established, that the higher the concentration of mercury in standard solution is, the higher impulse counts is obtained for European aspen. This reversal of the dependence is noticeable for second analyzed species.
