介绍了一种用氧弹燃烧灰化技术和酸碱滴定法测定腐植酸硼肥中硼的方法。在高压、高纯氧环境中利用氧弹灰化技术对样品进行预处理,灰化产物利用碱液进行吸收,采用酸碱滴定法测定试样中硼含量。通过标准加入法进行验证,结果表明,本方法灵敏度高,重现性较好,回收率平均为97.5%,标准偏差为1.49%,可直接用于有机物中硼的测定。 A method for determination of boron in humic acid boron fertilizer by oxygen bomb combustion ashing technique and acid-base titration method is introduced. In the high pressure, high oxygen environment using oxygen bomb ashing technology for pretreatment of samples, the use of lye ash absorption, the determination of boron content by acid-base titration. The results showed that the method has high sensitivity and good reproducibility. The average recovery was 97.5% and the standard deviation was 1.49%, which could be directly used for the determination of boron in organic compounds.
