GB/T 15076.2-2019 Methods for chemical analysis of tantalum and niobium—Part 2:Determination of niobium content in tantalum—Inductively coupled plasma atomic emission spectrometry and stratography gravimetry
Abstract
This part of GB/T 15076 specifies the determination of niobium content in tantalum by inductively coupled plasma atomic emission spectrometry and chromatographic separation-weight method. This part is applicable to the determination of niobium content in tantalum and tantalum hydroxide, tantalum oxide, tantalum carbide, and potassium fluotantalate. **Method I: Inductively Coupled Plasma Atomic Emission Spectrometry** **Determination range**: 0.001% to 2.00% **Method II: Chromatographic Separation-Weight Method** **Determination range**: >2.00% to 20.00%
