摘　　要：建立了微波消解-电感耦合等离子体发射光谱法(ICP-OES)测定有机-无机复混肥中砷、镉、铬、汞、镍和铅等6种重金属的方法。优化了微波消解条件,讨论了光谱干扰及消除。方法回收率在80.0%～103.3%之间,相对标准偏差均<6.8%。该方法简便快速,结果准确可靠。A method was established for simultaneous determi- nation of As,Cd,Cr,Hg Ni and Pb by ICP-AES with micro- wave-assisted digestion. Microwave-assisted digestion condi- tions were optimized and effects of concomitant ions were studied. This method is efficient, facilitated and accurate. The recoveries rate of this method were between 80. 0% and 103.3%, while relative standard deviation was lower than 6.8%.
