标准编号：ISO 11048:1995

中文名称：土壤质量 水溶性和酸溶性硫化物的测定.

英文名称：Soil quality — Determination of water-soluble and acid-soluble sulfate

发布日期：1995-05

标准范围

规定了风干土壤和类似土壤材料的水和酸提取物的制备程序。这些提取物的硫酸盐含量通过重量分析法测定，在重量分析法中，向水或酸提取物中添加氯化钡，并干燥和称重硫酸钡沉淀物。然后根据分析中使用的材料质量和沉淀的硫酸钡质量计算硫酸盐含量。适用于所有类型的风干土壤。

Specifies procedures for the preparation of water and acid extracts of air-dried soils and soil-like materials. The sulfate content of these extracts is determined by a gravimetric method in which barium chloride is added to the water or acid extract and the precipitate of barium sulfate is dried and weighed. The sulfate content is then calculated from the mass of the material used in the analysis and the mass of barium sulfate precipitated. Applicable to all types of air-dried soils.
