摘要
将采集油烟的滤筒 ,移入比色管内已定容的CCl4溶剂中 ,将比色管置于超声器上清洗 2 0min ,用非分散红外光度法可直接测定清洗液中油烟的含量。实际样品测定结果表明 ,该方法简便易行 。
A filter drum with collected oil smoke is put into CCl 4 solution in a colorimetric tube and then an ultrasonic device is used to clean the colorimetric tube for 20min.The content of the oil smoke in the cleaning liquid is determined directly by non dispersive infrared photometry.It is shown by the test result of the actual sample that the method is simple and feasible with a better accuracy.
