摘要
主要论述了含金样品经过高温焙烧,王水溶解,泡沫塑料震荡分离富集,硫脲盐酸溶液解脱后,以抗坏血酸作为基体改进剂,用石墨炉原子吸收光谱仪进行分析测试样品中金的含量。通过对实验过程中各个流程因素的对比实验,确定了最佳的分析实验条件,保证了测试结果的准确性。
After high temperature roasting, dissoluting by the aqua regia, plastic foam separating and enric-hing in concussion, thiourea and hydrochloric acid solution releasing, using ascorbic acid as a matrix modi-fier, test samples content gold were analyzed by using graphite furnace atomic absorption spectrometer. Through the contrast of each analyzing experimental process factors , the optimal analytical conditions were found, the accuracy of test results could be ensured.
