中文摘要: 本文建立了用盐酸、硝酸、氢氟酸和高氯酸的混合酸溶解样品,采用电感耦合等离子体发射光谱法(ICP-OES)测定废钒触媒中钒含量的分析方法。该方法确定了最佳溶样方法和仪器的最佳条件。在选定的操作条件下,钒的检出限0.026μg/mL。相对标准偏差(n=11),RSD<1%,加标回收率在98.85%-101.30%之间。用该法测定废钒触媒中钒的含量,流程短,易操作,结果令人满意。
Abstract:A method for the determination of vanadium in waste vanadium catalyst by inductively coupled plasma optical emission spectrometry (ICP-OES) was developed. The sample was dissolved with mixed acid of hydrochloric acid nitric acid hydrofluoric acid and perchloric acid and the content of vanadium in waste vanadium catalyst was determined by ICP-OES. The optimum sample dissolution method and the optimum conditions of the instrument were determined by this method. Under the selected operating conditions, the detection limit of vanadium is 0.026μg/mL. The relative standard deviation (n=11), RSD<1%) and the recovery rate of 99.20% -101.30% were obtained. This method can be used to determine the content of vanadium in waste vanadium catalyst. The process is short and easy to operate. The results are satisfactory.
