| Abstract: | The method for direct determination of neodymium, iron and boron in Nd-Fe-B permanent magnetic materials by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) was studied and suitable analytical lines were selected. The interference from matrix elements in samples was diminished by matrix matching method. The memory effect of the determination of boron by ICP-AES was discussed and was eliminated by way of detecting and subtracting blank value from testing result of samples frequently. The method was applied to the determination of Nd, Fe and B in Nd-Fe-B permanent magnetic materials samples with a precision of RSD 0.62%, 0.56% and 0.90%, respectively. |
