摘要
利用自制微型滴定装置,对水的硬度进行一系列微型化滴定实验探索,以此来确定试剂的最少用量,当试剂用量降低到原用量的1/2和1/10时仍能得到符合常量分析准确度和精密度要求的实验结果,从而节约了实验试剂,实验经费和时间,具有良好的经济效益和社会效益.
Using the self—restraint miniature titration apparatus,we have carried on a series of microminiaturized titrate experiment to explore the hardness of water,when the amount of the reagent was cut down to1/2 and 1/10 of its original amount,the experimental result was obtained which accorded with constant analysis degree of accuracy and the precision demanded.The experimental reagent,founds and time were saved.It has good economic social benefit.
