Megjegyzések:	Sample preparation and measurement methods suitable for serial measurements were elaborated for the determination of the NO3 - , SO4 2- and Cl- contents of soil and plant samples using single column ion chromatography. In the case of soil samples, the use of a 1:5 aqueous extract (1 h extraction time) was found to be the best method of sample preparation for serial measurements on the NO3 - , SO4 2- and Cl- contents, which could be measured simultaneously from the extracts. Although the soluble SO4 2- content of the soil could be measured equally well in aqueous and 0.01 M CaCl2 extracts, water was judged to be the best extracting agent, as this allowed the quantities of Cl- and NO3 - to be measured at the same time. An optimum method was also elaborated for the determination of the NO3 - , SO4 2- and Cl- contents in plant samples (wheat grains, wheat straw, strawberries). In correctly prepared aqueous extracts, NO3 - , SO4 2- and Cl- contents could again be successfully determined in parallel. Standard deviation was recorded to determine the reproducibility of ion chromatography measurements on soil and plant extracts. In all cases the CV% value characteristic of the deviation was below 11.45, and ranged from 1-6% in identical extracts. The applicability of the ion chromatography technique for determining the anion contents of soil and plant extracts was investigated with the help of recovery tests. In all cases a high percentage of the added ions was recovered.
