摘　　要：用镧盐涂覆石墨管,大幅度提高测定血清铬灵敏度,选用硝酸铵基体改进剂,消除干扰,方法简便快速。灵敏度和精密度高。It is reported in this paper that different kinds of coated graphite tubes was tested for optimization of operating condition for determination of chromium in serum by GFASS. The matrix effect and the background of the sample was eliminated by adding NH_3NO_3 and Triton X-100. The method is suitable for the rapid determination of chromium in serum of cancer patients.
