摘要
采用电感耦合等离子体发射光谱法,同时测定高铁三水铝土矿中的Si、Fe、Al、Ti、Mn、V、As、P等元素。对影响其光谱测量的各种因素进行了较为详细的研究,确定了最佳的试验测定条件。结果表明,该方法的检出限为0.0012-0.061μg/mL,回收率为95.4%-107.4%,主量元素相对标准偏差在1%-3%之间,次量元素相对标准偏差在2%-6%之间。该方法准确、快速、简便,应用于高铁三水铝土矿的测定,结果令人满意。
Inductively coupled plasma atomic emission spectrometry has been adopted to simultaneous determination of the elements Si, Fe, Al, Ti, Mn, V, As, P, etc. in high-iron gibbsite with its all influencing factors being researched in detail and the optimal conditions for experiment determination being confirmed too. The conclusion showed that the spectrometry being applied to the determination of high-iron gibbsite with a satisfactory result is accurate, fast and convenient with its detection limit of 0. 0012- 0. 061μg/mL, recovery ratio of 95. 4%-107. 4%,relative standard deviation of major elements between 1% -3% and that of minor elements between 2%-6%.
