摘要:采用微波消解-ICP-OES法检测木质活性炭中金属铁含量,探讨了射频功率、观测高度、雾化气流量和进样量对相对灵敏度的影响。结果表明,该方法检出限为0.03 mg/L,加标回收率97%,相对标准偏差(RSD,n=6)0.87%,标样测定结果与认定值相符合,且与国标法相比,利用该法检测木质活性炭中金属铁含量更加准确、可靠。
The determination of iron in wood activated carbon by microwave digestion-ICP-OES and dis- cussed the influence of RF power, observation height, nebulizer gas flow and injection volume to relative sensitivity. The results show that the detection limits is 0.03 mg/L, the recovery is 97% and relative standard deviation is 0.87% (n = 6) ,the analytical result of standard sample was in agreement with affirmation. Compared with national standard method, this method which used to determinate iron in wood activated carbon is more accurate and reliable.
