摘要
大米中的镉含量测定是当前食品安全检测工作的热点。原子吸收分光光度计测定法依然是国家标准中指定的仲裁测定法之一。文章总结分析了湿式消解、压力罐消解、干法灰化、微波消解4种方法的各自利弊。并着力于对湿式消解法在细节方面进行优化,以期节约检测成本,缩短检测流程,提高检测效率,为粮油检测部门日常检测提供一套更为快速的前处理和定标方案。
The determination of cadmium in rice is a hot spot in the current food safety testing work.Atomic absorption spectrophotometry is still one of the arbitration methods specified in the national standard.For sample pretreatment,this paper summarizes the advantages and disadvantages of wet digestion,pressure tank digestion,dry ashing and microwave digestion.And focus on the wet digestion method in the details to optimize,establish a set of effective,save detection costs,shorten the detection process,improve detection efficiencyEstablish a more rapid pre-processing and calibration scheme for daily inspection of grain and oil inspection departments.
