摘要
根据中国地质调查局正在组织开展全国性1:50000～1:250000地下水污染调查评价工作中对重点区要求必测的无机元素项目要求,用天然基体的地下水制备地下水无机多元素测定监控样。采集的地下水经初步分析后,进行有关组分的添加处理,制备需要研制的实验室监控样品。通过均匀性和稳定性检验,判定监控样的均匀性良好,在监测期间内性质稳定。探讨了该监控样在地下水无机元素测定质量监控工作中可以用于校准仪器、评价测量方法的准确度和用作分析质量保证。
Based on technical requirements for inorganic element analysis in the national 1：50000 ～1：250000 investigation and evaluation of groundwater pollution survey project,quality control samples for inorganic multielement analysis of groundwater were prepared.The matrixes of the samples were taken from natural groundwater and the components for certification were added artificially.The homogeneity and stability of the samples were tested with satisfactory results.The quality control samples have been applied to the instrument calibration,evaluation of the analytical methods and quality control in inorganic multi-element analysis in groundwater samples.
