摘要
Abstract
Sample pretreatment was carried out using alkali melting acidification method,and inductively coupled plasma optical emis-sion spectroscopy(ICP-OES)was used to rapidly analyze the content of tungsten and molybdenum elements in geological ores.By se-lecting the optimal analysis conditions and suitable analysis lines,the interference of the matrix is eliminated during detection,ensuring the accuracy of the detection results.The detection limits of tungsten and molybdenum are 0.00 1 μg/mL and 0.00 2 μg/mL,respec-tively,and the detection ranges are 0.001%～6.00%and 0.001%～5.00%for molybdenum content.The geological ore reference materials were measured,and the measured values were consistent with the standard values.The relative standard deviation was within 0.22%～4.18%and the recovery rate was within 95%～102%.关键词
