| 摘 要： | 采用电感耦合等离子体原子发射光谱法（ ICP－AES ）探讨硼铸铁中硼的测定。以盐硝混酸（3＋1＋6）和硫酸溶液（1＋3）在低温下溶解样品，溶解完毕后定容，在设定的仪器工作条件下测定。硼检出限为0．027 mg／L。用该方法可测定硼铸铁中0．0034％～0．38％硼含量，连续测定6个平行样测定结果的相对标准偏差均小于4．52％，其回收率在93％～108％、相对误差在3．03％以内。

| Abstract: | Using inductively coupled plasma atomic emission spectrometry （ ICP-AES ） , the determination of the boron cast iron boron was discussed.With salt nitrate mixed acid （ 3＋1＋6 ） and sulfuric acid solution （ 1＋3 ） sample dissolved in low temperature, the boron was measured after the completion of the constant volume dissolved, under the working conditions of settinginstrument.Boron detection limit was 0.027 mg/L.Using this method can determine the boron cast iron by 0.0034%~0.38% boron content, continuous determination of six parallel sample the determination results of relative standard deviation was less than 4.52%, the recovery was 93%~108%, and relative error was within 3.03%. |
