摘要
本法采用镍为基体改进剂,消除较复杂试样的基体干扰,直接用石墨炉原子吸收法测定岩石矿物中痕量铊和镓。该法简便、快速、准确。国家一级标样测定值与推荐值吻合。对于镓的测定经过100多个实际样品考查分析质量符合要求。
By taking Ni as a matrix improver, remove matrix disturbance of relatively complcated sampies and determine directly trace Ti, Ga in rocks and minerals by using atomic absorption method with graphite furnace. This method is simple, high—speed, and accurate. The determed value and recommended value reach the state standard A. Morn than one hundred samples of Ga were determed and all the analytical results accord with requirements for quality.
