在复混肥料氯离子检测中由于氯含量的不确定性,既使严格按照国标GB15063-2009的沉淀滴定法进行检验,也容易造成极大的误差。在实验过程中,如何准确判定滤液中氯离子的含量,而采取相应的取样量,如何注意第一个实验细节,都是保证检验结果数据准确性的必要环节。
Due to the uncertainty of the chlorine content in the compound fertilizer chloride ion test, even in the strict accordance with the national standard GB15063-2009 precipitation titration test, but also easily lead to great errors. In the process of experiment, how to accurately determine the content of chloride ion in the filtrate, and take the appropriate sample size, how to pay attention to the first experimental details are necessary to ensure the accuracy of the test data link.
