中文摘要: 研究分析干扰螺旋藻片中铅含量测定的影响因素，依据样品特点及基体改进剂作用机理，选择硝酸钯、硝酸镁、抗坏血酸作为基体改进剂协同使用，优化试验条件为：2 g/L硝酸钯溶液、1 g/L硝酸镁溶液与5%抗坏血酸溶液以3∶3∶4（体积比）湿法添加，灰化温度提高至1200℃，原子化温度1900℃，实现了螺旋藻片中铅含量的准确定量。
Abstract:The interfering factors in determination of lead in Spirulina tablets were analyzed，based on sample characteristics and the matrix modifier chemical mechanism，we selected palladium nitrate，magnesium nitrate and ascorbic acid as matrix modifier.The optimize conditions were as follows：added palladium nitrate solution 2 g/L，magnesium nitrate solution 1 g/L and ascorbic acid solution 5%：a proportion of 3∶3∶4（volume ratio），ashing temperature to 1 200℃，atomization temperature 1 900℃，achieved the accurately quantitative in spirulina tablets lead content determination.
