提出了一种新的增感机理:在表面活性剂的cmc前,气溶腔形成过程中被测离子在小液滴上富集产生增惑;cmc后富集作用减小,但被测离子和表面活性剂形成胶团化物产生新的增感,火焰部分表面活性剂的不完全燃烧增强了火焰的还原性是增感因素之一。
A new mechanism of sensitization was proposed: before the cmc of surfactant, the measured ions were enriched in small droplets during the formation of gas-filled cavity, and the enrichment effect was decreased after cmc. However, the measured ions The formation of micelles with surfactant produces new sensitivities. The incomplete combustion of flame partial surfactants enhances the reduction of flame and is one of the sensitizing factors.
