Concentrations of trace elements in some drinking waters were determined using the X-ray emission spectroscopy. Water samples were collected near Rijeka, the most industrialized centre in the northern part of the Yugoslav coast, to find out if concentration of heavy metals in water are within permitted limits. Since concentrations of heavy metals in natural water are quite low, it was necessary to preconcentrate the water before the analysis. Two techniques of water samples preparation were used depending on the elements to be analyzed: precipitation by the APDC (amonium-pyrrolydine-dithiocarbamate) (for Fe, Ni, Cu, Zn, As, Pb and Hg). complexation with the APDC followed by the adsorption on activated carbon (for U).
采用X射线发射光谱法测定了一些饮用水中的微量元素浓度。在南斯拉夫海岸北部工业化程度最高的中心里耶卡附近采集了水样，以查明水中重金属浓度是否在允许范围内。由于天然水中重金属的浓度相当低，因此在分析之前有必要对水进行预浓缩。根据要分析的元素，使用了两种水样制备技术：用吡咯烷二硫代氨基甲酸铵（APDC）沉淀（用于铁、镍、铜、锌、砷、铅和汞）；与APDC络合，然后吸附在活性炭上（用于铀）。
