摘要
2017年5月1日开始实施的《HJ828-2017水质化学需氧量的测定重铬酸盐法》将代替GB/11914-89标准。通过比对新旧标准的异同,分析了新标准的改进对分析结果的影响以及如何掌握新标准分析方法的关键环节。
The old standard of water quality-determination of chemical oxygen demand-dichromate method（ GB/11914-89） would be replaced by the new standard of HJ828-2017. The similarities and differences of these two standards were compared. The impacts of the improvements of the new standard were examined. The keys of accurately using the new standard were identified.
