采用离子色谱法测定了10种不同类型肥料中的水溶性氟含量,并组织8家实验室进行了实验室比对工作。试验结果表明,肥料中水溶性氟含量平均值与重复性标准差和再现性标准差存在线性关系,随着水溶性氟含量的增大,重复性标准差和再现性标准差也相应增大。
Abstract The content of water-soluble fluorine in ten different types of fertilizers is determined by ion chromatography, and eight laboratories are organized to carry out interlaboratory comparison. The results indicate that there is a linear relationship between the average concentration of water-soluble fluorine in the fertilizer and the repeatability standard deviation and the reproducibility standard deviation. With the increase of water-soluble fluorine content, the repeatability standard deviation and reproducibility standard deviation increase too.
