摘要
采用市售5 mL微型滴定管,对分析化学实验中的部分滴定分析实验进行了微型化探索.试剂用量可减少为常规用量的五分之一,且不影响分析结果的准确度和精密度.微型滴定法既可大幅减少试剂用量及废液排放量,又培养了学生更高的分析操作技能,社会经济效益显著.
Miniburet of 5mL was applied to explore the miniature titration experiments in analytical chemistry. Compared with conventional titration, advantages of minianalysis include over 80% of cost reduction, much less amount of hazardous wastes discharging and better training of student＇ s skills. Precision and accuracy of minititration meet the demands of analytical chemistry.
