摘要
甲醛检测结果的准确性直接关系到人民群众的健康,2020年GB 50325—2020《民用建筑工程室内环境污染控制规范》正式将AHMT分光光度法修改为仲裁法。目前,有多项研究显示该方法的试验条件会影响到甲醛检测结果的准确性,而且检测的结果与人民群众的健康是息息相关的。在此基础上,项目组主要通过改进AHMT分光光度法的试验条件,优化试验吸收液的稳定性、显色剂用量、显色剂的反应时间、显色剂的反应温度等影响因素,并验证了检出限、精密度和准确度。
The accuracy of formaldehyde detection results is directly related to the health of the people.In 2020,“Code for Indoor Environmental Pollution Control of Civil Building Engineering”(GB 50325—2020)officially revised the AHMT spectrophotometric method to the arbitration method.At present,multiple studies have shown that the experimental conditions of this method can affect the accuracy of formaldehyde detection results,and the detection results are closely related to the health of the people.On this basis,the project team mainly improved the experimental conditions of AHMT spectrophotometry,optimized the stability of the experimental absorption solution,the amount of chromogenic agent,the reaction time of the chromo-genic agent,the reaction temperature of the chromogenic agent,and other influencing factors,and verified the detection limit,precision,and accuracy.
