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 ,结果准确可靠。RSD为 6 2 % ,回收率在 96%～ 10 2 %范围。
A flame atomic absorption spectrometry for the determination of trace iron in high effective red phosphorus fire retardant has been developed The sample is dissolved in HNO 3-Br 2,and then dry filtered Iron is determined by flame atomic absorption spectrometry RSD is 6 2% The recovery is 96%-102%
