Abstract: | [ Objective ] To determine heavy metal content in honeysuckle. [ Method ] A simultaneous determination method of heavy metals, including Cu, As, Cd, Pb and Hg, in honeysuckle by ICP-MS combined with microwave digestion was established. Sample was digested by microwave and then analyzed by ICP-MS for determination of 5 heavy metals. [ Result] The correlative coefficients of calibration curves for analytes were all above 0.999 5. The recoveries were in the range of 93.5% - 98.6% , and RSDs were not more than 4.82%. [ Conelusion] The method is convenient, quick, accurate and highly sensitive for the determination of heavy metals in honeysuckle. |
