摘要
用火焰原子吸收光谱法测定高效红磷阻燃剂中痕量铁 ,样品经溴化硝酸溶解 ,干滤后 ,用空气 -乙炔火焰测定 ,实验结果准确可靠 .RSD为 6 .2 % ,回收率在 96 %～ 10 2
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%.
