摘要
用火焰原子吸收光度法对高品位硫精矿及其烧渣中的钙进行测定,加入抗坏血酸和镧溶液消除对其测定产生的干扰,测定的线性范围为0～5mg/L,相关系数R=0.97～0.98,RSD(n=11)=4.60%,加标回收率在97%～105%之间,测定结果重现性较好。
To determine the calcium content in high grade pyrite concentrate and cinder by flame atomic absorption speetroscopy, adding ascorbic acid and lanthanum solution to eliminate the disturbance to the determination. With the linearity range to 0～5mg/L,correclative coefficient R=0.97～0.98 RSD（n=1）=4.60%, labelingrecovery of the ratio is between 97%～105%, and the reproducibility result is comparatively satisfactory.
