摘　　要：标准滴定溶液浓度的不稳定会导致检验结果不准确,标准滴定溶液的储存有效期对浓度会产生影响。对《化学试剂标准滴定溶液的制备》(GB/T 601-2016)提及的27种标准滴定溶液进行储存有效期研究,发现5种标准滴定溶液储存有效期与标准规定不一致,给出其储存有效期的建议,为GB/T 601-2016提供技术补充。The instability of the concentration of the standard titration solution leads to the inaccurate test results,and the storage validity period of the standard titration solution will affect the concentration.Research on the storage validity period of 27 standard titration solutions mentioned of“Chemical Reagent-Preparations of reference titration solutions”(GB/T 601-2016),we found that the storage validity period of 5 standard titration solutions was not consistent with the standard provisions,and this paper puts forward suggestions on the shelf life of products,which provides technical supplement for GB/T 601-2016.
