Abstract

Trace elements (Cu, Zn, Fe, Ca, Mg, Mn, Al, K, Ba, P, Sr, Cd, V, Cr, Ni, Pb and Co) concentrations in the drinking water of KBD-affected and non-affected areas were measured using ICP-AES. The RSD of this method was between 0.80% and 2.83%, and the analytical results of the reference samples were consistent with the certified values. The method was simple and accurate. The results indicated that there is an obvious difference in trace elements concentrations between KBD-affected areas and non-afffected areas. The results provided a scientific theoretical basis to improve the conditions of drinking water in KBD-affected areas in Tibet.

摘要

采用电感耦合等离子体发射光谱法（ICP-AES）测定了大骨节病病区和非病区饮用水中微量元素（铜、锌、铁、钙、镁、锰、铝、钾、钡、磷、锶、镉、钒、铬、镍、铅和钴）的含量。该方法的相对标准偏差在0.80%至2.83%之间，标准样品的分析结果与认定值相符。该方法简便准确。结果表明，大骨节病病区与非病区的微量元素含量存在明显差异。研究结果为改善西藏大骨节病病区的饮用水条件提供了科学理论依据。
