研究了用碳粉、碳酸钙、氧化铜和氧化铍作缓冲剂同时测定钛基复合材料中的镍、铁、钼、锰和硼的发射光谱法,选择铍作内标线,不需分离、不需化学处理,直接压样于杯形的石墨电极中,具有简便、快速、准确.对测定条件、干扰因素进行了研究,从而建立测定镍、铁、钼、锰和硼的新方法.镍、铁、钼、锰和硼的分析线分别为300.36,248.33,315.82,260.57和249.68 nm,内标线选择为铍的298.61 nm,镍、铁、铝、锰和硼的线性范围分别为0.003%～0.30%;0.001%～0.20%;0.003%～0.30%;0.001%～0.20%;0.001%～0.20%.镍、铁、钼、锰和硼的检测限分别0.003%,0.001%,0.003%,0.001%,0.001%,其回收率在95.80%～104.8%范围内,当n=9时,相对标准偏差RSD均小于5%.用于样品的测定取得了满意的结果.
