| 摘 要： | 化学需氧量,是评价水体污染程度的一项重要综合性指标。论文探讨了在环境工程专业教学中,克服回流滴定法测定时间长、教学费用高、运行不安全等缺点,发挥微波消解法准确、快速、省钱的优点,利用"微波闭式COD消解仪"进行水样中化学需氧量测定,研讨性学习掌握COD测试的原理、条件和误差,不仅可以满足教学大纲基本要求,而且能培养学生创新意识和能力。

| Abstract: | Chemical oxygen demand is an important comprehensive performance index of estimating pollutant level in waters.COD is conventionally determined by Thermal Reflux Method,which costs long time and much money.Even worse,the traditional method operates insecurely.By contrast,Microwave Digestion Method has many advantages,such as precise,fast and money-saving.The paper discussed the two methods of COD determination(Microwave Method for emphasis),and utilized the new method to do some experiments.The device of th... |
