摘　　要：用乙酰丙酮溶液将CODcr反应管制成标准反应管,CODcr消解器加热回流30 min,DR/2010分光光度计比色测定甲醛含量。方法精密度、准确度满足甲醛测定的分析要求。The standard CODe, retort was prepared by acetyl - acetone acid, heated and eireumflueneed by the CODer reactor for 30 minutes. Then the content of formaldehyde was mesured by the DR/2010 prismatic photometer. The accuracy and precision of the improved method conformed to the requirements of formaldehyde determining.
