     摘要目的测定三磷酸腺苷二钠的水分含量。方法卡尔费休氏法：①采用国产卡氏试剂，以ψ(乙二醇∶甲醇)=60∶40为溶剂滴定；②采用进口(双溶液)卡氏试剂滴定。结果两种试剂测定的回收率分别为96.0%,RSD=4.9%(n=10);99.0%, RSD=35%(n=11),样品测得结果相符。结论国产与进口的卡氏试剂均可用于三磷酸腺苷二钠的水分含量测定，方法简便，准确。适用于药品的质量控制。

    Abstract To determinate the water content of adenosine triphosphate disodium reagent by solvent titration. Homemade Karl Fishcher reagent with glycolmethanol (40∶60) and imported Karl Fischer (Hydranal) reagent (twodiscrete solution) were used and the results compared. Average recoveries for homemade reagent titration and imported reagent titration were 96.0% (RSD=4.9%, n=10) and 99.0% (RSD=3.5%, n=11), respectively.
