【摘要】 本法采用氯化把-销酸镁联合基体改进剂，以四氢味喃作为溶剂将菜籽油溶解后直接导入石墨炉原子吸收分光光度计中进行测定，避免了因消化引入的污染和损失，方法灵敏度高，结果重现性较好，操作简便快速。更多还原

【Abstract】 PdCl2,-Mg (NO3)2 was ed as a united matrix modifier for determination of total arsenic in rapeseed oil. Samplescan be directly determined by GFAAS after dissolved in tetrahydro furan (C4H8O). The experiments showed the loss and contamination of elements caused by digesting decreaed, as well as higher sensetivity and repetitiveness acquired. The method is easy andrapid for determinating total arsenic in rapeseed oil.更多还原
