摘　　要：利用微型滴定法测定地表水中溶解氧的含量,并对微型实验和常量实验的平行测定结果进行了比较。微型滴定的测定结果准确可靠,微型实验具有现象明显、节省试剂、分析速度快等特点,能降低实验成本,提高学生的创新能力,完全符合绿色化学的理念,值得推广。The content of dissolved oxygen in surface water was determined by micro titration. Parallel determination results of microscale experiment and constant experiment were compared. The results of micro titration were accurate and reliable. Microscale eperiment has such characteristics as obvious phenomenon, saving reagents, fast analysis etc. So the cost was reduced and the innovative ability of students was improved by full compliance with the concept of green chemistry. Microscale experiment is worth promoting.
