摘要
对CODCr检测的标准方法进行了改进,用低成本药剂替代高成本药剂,用无毒试剂替代剧毒的硫酸汞,缩短了实验时间,有效地降低了实验成本。同时对CODCr实验废液中的银进行回收,不仅实现了资源的再生利用,还减少了环境污染,符合清洁生产的要求。
The standard method for CODCr test was improved,using low cost reagent instead of high cost reagent,with non-toxic reagent instead of highly poisonous mercury sulfate,thus the experiment time was shortened and the experimental cost was effectively reduced.At the same time,the silver in the wastewater from CODCr experiment was recovered,as a result not only recycling of resources was realized,but also environmental pollution was reduced,complying with the requirements of cleaner production.
