微型滴定实验装置的设计与应用研究

微型化实验是20多年来国内外广泛开展的一种化学实验方法,其特点是仪器微型化和试剂用量少。本实验利用自制微型滴定装置,对分析化学实验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1/4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。

Applied research and design of miniature titrate installation

Micro scale chemical experiment has been widely used in recent 20 years.It is characterized by the microminiaturization of instrument,and less reagent.This experiment uses the self-restraint miniature titration apparatus,carrid on a series of microminiaturized titrate experiment to the analytical chemistry experiment to explore,when the amount of the reagent was cut down to 1/ 4 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.
