本文使用国产家用微波炉及自制聚四氟乙烯密闭容器分解人发,其最佳条件是:样品为0.2000克时,加0.5毫升HNO_3及1.5毫升H_2O_2,以500瓦功率作用6分钟,分解后定容至10毫升。Fe、Cu、Ca、Mg、用火焰AAS法测定,塞曼校正背景,Zn用参考光束(σ分量)火焰AAS进行测定,Cd用恒温平台石墨炉(STPF)AAS法测定,镧盐作改进剂。与常规分解法的结果相比,该方法不仅简便、快速,且具有良好的准确度和测定精密度。 In this paper, homemade microwave ovens and self-made polytetrafluoroethylene containers were used to break human hair. The optimal conditions were as follows: when the sample was 0.2000g, add 0.5ml of HNO3 and 1.5ml of H202, To 10 ml. Fe, Cu, Ca, Mg were determined by flame AAS method, Zeeman corrected background, Zn was measured by flame AAS with reference beam (σ component), Cd was determined by STPF AAS method, lanthanum salt was used as modifier . Compared with the results of the conventional decomposition method, the method is not only simple and fast, but also has good accuracy and precision.
