摘　　要：目的评价微型滴定法在饮用水硬度测定中的效果。方法利用刻度吸管和医用输液器自制微型滴定装置,对饮用水的硬度进行测定;同时将微型滴定法与常量滴定法的平行测定结果进行比较。结果微型滴定法测定水质硬度相对偏差小于2%,微型滴定法的精度高于常量滴定法。结论将微型滴定法用于测定水质硬度,方法可靠,并能节省成本。Objective To evaluate the effects on the determination of drinkable water hardness by micro - titration. Methods Using homemade micro - titration device made of graduated pipette and medical infusion research on the drinka- ble water hardness ; And compare micro - titration with conventional - titration results. Results It showed that the relative standard deviation was less than 2% on the determination of water hardness by micro -titration ,and the accuracy by micro - titration was higher than conventional - titration. Conclusion The micro - titration was reliable and save cost. It ean be used for determination of the water hardness.
