| 摘 要： | 用硝酸-过氧化氢作消解液,用微波消解法处理样品,采用电感耦合等离子体原子发射光谱法测定了鲍鱼中锌、铁、锰和铜的含量。测定结果的相对标准偏差RSD<4%,加标回收率在97.4%~105.0%之间,检出限在0.764~1.539μg/L之间。该法快速、稳定、准确,结果令人满意。

| Abstract: | The samples were microwave-assistedly digested with nitric acid-hydrogen peroxide for ICP-AES determination of zinc,iron,magnesium and copper.The RSD was less than 4%,and the spike recoveries were in 97.4%~105.0%.The determination of limits were within 0.764~1.539 μg/L.This method was fast,stable and accurate,and suitable for determination of the 4 microelements in haliotis. |
