中文摘要: 试样以王水和氢氟酸为消解试剂,经微波消解,采用电感耦合等离子体原子发射光谱法测定水淬渣中的多种元素。试样在185℃的密闭容器中62min可以溶解完全;消解液成分的干扰可以通过选择合适的分析谱线消除;回收率99.8%~107.8%,相对标准偏差为0.68%~8.65%(n=5), 方法检出限满足分析要求。结果表明,方法操作快速简便,可满足水淬渣中多种元素同时测定的要求。
Abstract:The sample was digested by microwave with Aqua and hydrofluoric acid, and multiple elements in Water-chilled dreg was determined by Inductively coupled plasma atomic emission spectroscopy. The sample can be dissolved completely in an airtight container at 185 °C for 60 Min, the interference of the composition of the digestion solution can be eliminated by selecting the appropriate spectrum line, the recovery rate is 95.72%~106.89%, the relative standard deviation is 0.68%~8.65% (N = 5) , the detection limit meet the analytical requirements。 The results show that the method is fast,simple and accurate,and the method can be used for the determination of multiple elements in Water-chilled dreg.
