摘要
本文采用石墨炉原子吸收分光光度计测定柠檬酸中钙的含量.实验结果表明,吸光度与钙的浓度呈良好的线性关系,回收率在90.6%～115.4%之间,相对标准偏差为1.9%～4.4%,检出限为0.2ng/g,实验结果令人满意.
The Calcium in citric acid is determined by GFAAS. It indicates that there is a good linear relationship between absorption and concentration of calcium , its recovery is 90. 6%-115.4%, RSD 1.9%-4. 4%, LOD 0. 2 ng/g. The result is satisfactory.
