Efficiency of extractants to release As, Cd, and Zn from main soil compartments

Popis výsledku v původním jazyce

In this experiment, four single extraction procedures (aqua regia, HNO3, acetic acid, DTPA) were tested for the determination of extractable contents of As, Cd and Zn. 35 soils differing in their physicochemical properties and in total element contents were used in this experiment. Extractability of elements from soil samples varied following the individual elements and/or extraction agents used. The strong acids were not able to release the elements tightly bound into the silicate sample matrix. The concentrations of As, Cd and Zn determined in soil extracts by both mineral and organic acids covered in most cases the element portion representing more than one soil element fraction determined using SM&T sequential extraction procedure.
