| Abstract: | In this paper, the trace-ferrite in high-effective red phosphorus fire-retardant has been determinated by flame atomic absorption spectrometry (AAS).The sample, dissolved by bromated nitric-acid, is firstly filtered and then is determinated by AAS in air-acetylene flame. The experimental result is accurate and reliable. RSD is 6.18% and the recovery ranges from 96% to 102%. |
