摘　　要：GB/T 601-2016《化学试剂标准滴定溶液的制备》中规定,在标准滴定溶液标定、直接制备和使用时若温度不为20℃时,应对标准滴定溶液体积进行补正,所用分析天平、滴定管、单标线容量瓶和单标线吸量管等按相关检定规程定期进行检定或校准。在实际应用中,对不同温度下、不同滴定管及不同标准溶液滴定进行体积校正运算非常繁杂,本文通过内插法进行数据运算,并制成体积校正表,从而对标准滴定溶液体积的校正更加方便、快捷、准确。GB/T 601-2016 Chemical reagent-Preparation of reference titration solutionS,If the temperature is not 20℃for the calibration,direct preparation and use of the standard titrating solution,the volume of the standard titrating solution should be corrected,The Analytical Balance,Burette,single-line volumetric flask and single-line pipette are regularly calibrated or calibrated according to the relevant verification regulations.In practical application,It is very complicated to calibrate the volume of titrations at different temperatures,with different burets and with different standard solutions,In this paper,data operation is carried out by interpolation method,and the volume correction table is made,Therefore,the calibration of the volume of the standard titrated solution is more convenient,fast and accurate.
