本文通过对基体改进剂的研究,选用Sr Mg混合基体改进剂,测硼的灰化温度较高,抗干扰能力强,用以直接测定了高温镍基合金钢及饮用水中的痕量硼,并对标准参考物桃叶中的痕量硼进行了对照分析,结果满意。方法简便、灵敏,线性范围0—1.6μgB mL.特征量为200pg 1％吸收。 This article through the study of matrix modifier, the choice of SrMg mixed matrix modifier, boron ashing temperature is higher, anti-interference ability, for the direct determination of high temperature nickel-based alloy steel and trace amounts of boron in drinking water, And the standard reference peach leaf boron in a controlled analysis, the results are satisfactory. The method is simple and sensitive with a linear range of 0-1.6 μg B mL, with a characteristic amount of 200 pg 1% absorption.
