| 中文摘要: |
| 采用电感耦合等离子体原子发射光谱仪测定白炭黑中铜、锰、铁元素的含量。用浓盐酸代替常用的氢氟酸处理白炭黑试样，既可以有效避免氢氟酸残留对设备进样系统的损害，也可以起到减少雾化、去除溶剂干扰的作用，实现了3种待测元素的同时测定，线性关系好，精密度高，加标回收率和线性范围较好，结果可靠。 |
| 英文摘要: |
| The contents of copper，manganese，and iron elements in silica were determined by inductively coupled plasma atomic emission spectrometer.Using concentrated hydrochloric acid instead of commonly used hydrofluoric acid to treat silica samples could effectively avoid the damage of residued hydrofluoric acid to the equipment injection system，as well as reduce atomization and remove solvent interference，achieving simultaneous determination of three elements.The linear relationship was good，the precision was high，the recovery rate and linear range of the spiked elements were good，and the results were reliable. |
