摘　　要：研究了石墨炉原子吸收光谱法测定钛矿中微量铅的适宜条件,建立了石墨炉原子吸收光谱法测定钛矿中微量铅的方法。利用标准加入法和Zeeman效应校正背景,铅的线性范围为0- 70μg·L-1,回收率在90％-110％之间。用此方法对钛矿样品进行测定,结果满意。A GF-AAS method for the determination of trace lead in titanium ores was reported. Optimum analytical conditions were studied. Zeeman effect modulation was used for the background correction. Analytical results were calculated via the method of standard additions. Linearity was ranged in 0-70μg · L^-1 for Pb with recovery of 90%～110%. The method has been applied to the analysis of real samples with satisfactory results.
