摘要: |
铅矿、铅精矿、铅锌矿经混合酸(HCl+HNO3+HF)在高压密闭容器中微波消解后,通过电感耦合等离子体发射光谱法测定样品中的Zn、CaO、Na2O、MnO、MgO、As、Cu、Cd、Al2O3、K2O共10种组分。最佳仪器工作条件为:功率1.3 kW,等离子体气流量15 ml/min,辅助气流量0.2 ml/min,样品提升量1.5 ml/min。各元素相关系数均大于0.9991,回收率91.3%~109.7%。 |

Abstract: |
Lead ore,lead concentrates and lead-zinc ore were prepared by microwave assisted digestion in a pressurized vessel mixed with HCl,HNO3 and HF.Ten components in sample solution including zinc,calcium oxide,sodium,hydroxide,manganese oxide,magnesiumoxide,arsenic,copper,cadmium,alumina and potassium hydroxide were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES).The optimum working conditions of the instrument was obtained.The powder was 1.3 kW.The plasma gas flow rate was 15 mL/min.The auxiliary gas flow rate was 0.2 mL/min.The sample uptake amount was 1.5 mL/min.The correlation coefficient of all elements was over 0.9991 and the recovery rate was 91.3%~109.7%. |
