微波消解-ICP-AES法测定氧化铝中杂质元素

Determination of sodium,potassium,calcium,silicon,iron,titanium,manganese, zinc,copper,vanadium,chromium and boron in alumina by inductively coupled plasma atomic emission spectrometry with microwave digestion

采用微波消解法,将样品用磷酸溶解,用ICP-AES测定氧化铝中Na、K、Ca、Si、Fe、Ti、Mn、Zn、Cu、V、Cr和B等12种杂质元素,采用测定标样、加标回收试验和精密度试验证明该方法简便快速,准确可靠。

Alumina was dissolved in H3PO4 by microwave digestion, and Na, K, Ca, Si, Fe, Ti, Mn, Zn, Cu, V, Cr and B were determined by ICP - AES. The accuracy and feasibility of the method were tested by checking standard samples, standard addition recovery and precision. It is proved that this method is accurate, precise, easy and rapid to be used in routine analysis.
