摘要
采用氯化钯为基体改进剂石墨炉原子吸收法测定农产品中的镉。通过实验确定了基体改进剂的浓度以及最佳分析条件,分析了干扰因素及其消除情况。方法用于标准物质的测定,结果与标准值吻合,该方法用于实际样品的测定为福建省无公害和绿色食品的检测认证提供数据。
The cadmiums in the agricultural products were determined by GF-AAF method with palladium chloride as substrate modifier agent. The modifier agent's concentration and the optimum analysis conditions were established, as well as, the interference factors were discussed. This method was applied to the determination of cadmium in standard substance with satisfactory results, and applied to the actual sample determination with authentic datas for the testing of the green food and non-environmental pollution food of fujian province.
