| Abstract: | A new rapid method for determination of PFOS in PP plastics was reported in this paper.The sample was first cooled in liquid nitrogen and then smashed.The sample was weighed in a crucible and then filled with oxygen and ignited.The released fluorinated surfactant was absorbed using a solution of 3.2 mmol/L Na_2CO_3-1.0 mmol/L NaHCO_3,and detected by ion chromatography.The method is simple,quick and accurate,and it meets the requirements of related regulations. |
