红外分光光度法测定油烟新旧方法的比较研究及新标准的方法验证

Comparison of New and Old Methods for Determination of Lampblack by Infrared Spectrophotometry and Method Validation of New Standard

从测定原理、仪器设备、样品的采集及保存、样品制备、适用范围、试剂选择、空白试样、线性检验等方面对新标准HJ 1077—2019《固定污染源废气油烟和油雾的测定红外分光光度法》与旧方法GB 18483—2001《饮食业餐饮油烟排放标准(试行)》附录A进行讨论比较。并对新标准HJ 1077—2019《固定污染源废气油烟和油雾的测定红外分光光度法》从检出限、精密度和准确度三方面进行验证。

This paper discussed the new standard of the infrared spectrophotometry measure of determination of lampblack and oil mist in Waste gas from stationary sources which standard number is HJ1077-2019 and the old standard of the emission standard of cooking fume for catering industry which is put into trial use which standard number is GB18483-2001 in appendix A from several aspects:principle,instrumentation,sample collection and preservation,sample preparation,scope of application,reagent selection,blank sample and linearity.This paper also verified the new standard from three aspects:detection limit of the method,precision and accuracy.
