中文摘要 | 应用微波消解和电感耦合等离子体原子发射光谱法(ICP-AES)测定垃圾焚烧飞灰中的Cd,Cr,Cu,Mn,Ni,Pb,Zn等7种重金属元素。考察了飞灰的最佳微波消解条件,样品用HNO3-HCl-HF-H3BO3混合酸经微波消解后,溶解时间由原来的3~5h缩短到20min。选择合适的分析谱线,试液直接用ICP-AES同时测定上述7种重金属元素,所得各元素的线性关系良好,相关系数均大于0.9990,方法的检出限在0.0005~0.008μg/mL之间。所建立的方法应用于垃圾焚烧飞灰中痕量重金属元素的测定,回收率为94.8%~102.0%,相对标准偏差均小于5.58%。; A microwave digestion method was developed to determine the content of seven heavy metal elements including Cd,Cr,Cu,Mn,Ni,Pb and Zn in municipal solid waste incineration(MSWI)fly ash by inductively coupled plasma atomic emission spectrometry(ICP-AES).Microwave digestion systems and digestion conditions were investigated.when the samples were processed by microwave system in HNO_3-HCl-HF-H3BO3,the treatment time of MSWI fly ash was reduced from 3-5 h to 20 min.The appropriate analytical lines of elements were chosen and the elements were subsequently analyzed by ICP-AES.The results demonstrate that correlation coefficient is 0.999 0 or above,and the detection limits range from 0.000 5 to 0.008 μg/mL depending on the heavy metals.The method has been applied to the determination of trace heavy metal elements in MSWI fly ash with the recoveries of the elements from 94.8 % to 102.0 % and relative standard deviations(RSDs)of the results less than 5.58 %.; 国家高技术研究发展计划(863)项目(2002AA644010) |
