水质污染监测用7种阴离子溶液标准物质的研制

Preparation of 7 Kinds of Anions Solution Reference Materials for Monitoring Water Pollutants

使用电感耦合等离子体质谱仪、离子色谱仪等对研制的7种阴离子溶液标准物质原料的杂质进行定性和定量测定。通过杂质扣除法对原料纯度定值,并定量测定原料中7种离子间相互包含情况。采用重量-容量法对溶液标准物质准确定值。7种阴离子溶液可用于测定7种阴离子的分析方法确认与评价、成分定量分析等。为复杂微量样品中7种阴离子的测试参数提供参考标准,可以节约监测资源、提高效率。对监测环境水、饮用水和食品中重要阴离子和尽量保证样品检测的及时性具有重要意义。

The impurities in the raw materials of 7 kinds of anions solution reference material were determined qualitatively and quantitatively by inductively coupled plasma mass spectrometry,ion chromatograph,etc.The deduction impurity method was used to calculate definite values for raw materials.These ions were detected quantitatively which exist in each other as impurities.The weighting-volumetric method was used to define the characteristic value of this reference material.The 7 kinds of anions reference material can be used in the confirming and evaluation of analytic procedure,also quantitative analysis.It can be used as a reference standard for testing 7 anions parameters in complex micro-samples.It can economize on monitoring resources and improving efficiency.It plays an important role for monitoring anions which are present in environmental water,drinking water and food.It is also of great significance to ensure the timeliness of sample detection.
