食品中多元素的测定》中规定了食品中多元素测定的电感耦合等离子体质谱法(ICP-MS)和电感耦合等离子体发射光谱法(ICP-OES)，第一法适用于食品中硼、钠、镁、铝、钾、钙、钛、钒、铬、锰、铁、钴、镍、铜、锌、砷、硒、锶、钼、镉、锡、锑、钡、汞、铊、铅的测定;第二法适用于食品中铝、硼、钡、钙、铜、铁、钾、镁、锰、钠、镍、磷、锶、钛、钒、锌的测定。</p><p style="text-align:

style="text-indent:28px;line-height:150%">然而，要快速准确地完成重金属检测，除了要有先进强大的检测手段，还需要可靠的样品前处理技术。标准中列出了微波消解法和压力罐消解法，其中，微波消解法操作更快捷，处理量更大：</p><p style="text-indent:28px;line-height:150%"><strong>称取固体样品0.2g~0.5g(精确至0.001g，含水分较多的样品可适当增加取样量至1g)或准确移取液体试样1.00mL~3.00mL于微波消解内罐中，含乙醇或二氧化碳的样品先在电热板上低温加热除去乙醇或二氧化碳，加入5mL~10mL硝酸，加盖放置1h或过夜，旋紧罐盖，按照微波消解仪标准操作步骤进行消解。冷却后取出，缓慢打开罐盖排气，用少量水冲洗内盖，将消解罐放在控温电热板上或超声水浴箱中，于100 ℃加热30min或超声脱气2min~5min，用水定容至25mL或50mL，混匀备用，同时做空白试验。</strong></p><p style="text-indent:28px;line-height:150%"><strong> </strong></p><p
