X射线荧光光谱法测定富含硫砷钒铁矿石中的主次量元素OA北大核心CSCDCSTPCD
Quantification of Major and Minor Components in Iron Ores with Sulfur, Arsenic and Vanadium by X-ray Fluorescence Spectrometry
以钴(钴玻璃粉形式)作内标元素,准确测定全铁含量;加入保护剂硝酸铵和稳定剂碳酸锂,使硫转化为硫酸盐,有效地防止硫的挥发损失.通过条件实验,确立了样品熔融温度和钴玻璃粉的用量.选择经筛选的仪器测定条件,用X射线荧光光谱法同时测定铁矿石中TFe、SiO2、CaO、MgO、Al2O3、TiO2、P、S、Mn、V2O5、As、K2O、Na2O、Cu、Ni 等15种主次量元素.采用干扰曲线法对几乎完全重叠的Ti Κβ谱线与V Κα谱线进行谱线重叠校正,用理…查看全部>>
A method for the determination of 15 elements of Tfe, SiO2 , CaO, MgO, A12O3, TiO2 , P, S, Mn, V2O5, As, K2 O, Na2 O, Cu and Ni in high sulfur, arsenic iron ore by X-ray Fluorescence Spectrometry ( XRF ) was developed. Co in the form of cobalt glass powder was selected as the internal standard element for Fe determination. NH4NO3 served as the oxidant and Li2 CO3 as the protective agent and were used for preventing the sulfur from volatilizing. Multi-kinds o…查看全部>>
