| 摘 要： | 用硝酸、硫酸、氢氟酸分解处理样品,4%(V/V)硝酸提取,以硫酸铵(1%)+(0.5mg/mL)钒作为基体改进剂,塞曼效应扣除背景,石墨炉原子吸收光谱测定。该方法快速简便,相对标准偏差(RSD)为2.1%—2.9%,回收率在98.0%—106.0%之间。

| Abstract: | The geological samples were digested by HNO3,H2SO4 and HF and extracted by 4% HNO3（V/V）.The 1%（NH4）2SO4＋V5＋ was used as modification.The graphite furnace atomic absorption spectrometry with Zeeman background correction was applied to determinate trace Ga in the samples.This method was convenient.The RSD ranged from 2.1% to 2.9% and recoveries were between 98.0% and 106.0%. |
