Determination of harmful Heavy metals in Analog material of canner as packing materials by ICP-AES

【摘要】采用ICP-AES法测定四种罐头食品模拟物中的有害重金属铅、铬、镉、汞，并建立了10%乙醇模拟液和橄榄油模拟液的微波消解的方法，方法的回收率82.5%～99.6%之间，相对标准偏差为1.85%～6.51%，检出限在0.001mg/L到0.003mg/L以及0.01mg/kg到0.03mg/kg之间。该方法准确度高、简单、易操作，是测定罐头食品包装模拟物中有害重金属元素的有效方法。

Abstract: The content of lead,cadmium,chromium and mercury in analog material of canner was determined by ICP-AES,and the method of 10% ethanol analog material and olive oil analog material by microwave digestion was developed.The recovery of the method is between 82.5%～99.6%.The RSD is between 1.85%～6.51%.The limit of detection is between (0.001～0.003)mg/L and (0.01～0.03) mg/kg.The method is precise,simple and easy to operate for determination for these analog material.
