Определение массовой доли скандия, иттрия, РЗЭ и других примесных элементов в красном шламе методом волнового рентгенофлуоресцентного анализа

Abstract

Trace elements in red mud were assayed with fused lithium borate glass beads using Xray fluorescence spectrometry. Low dilution glass beads, which had a 1:4 sample-to-flux ratio, were prepared for determination of elements. Complete vitrification of 1:4 mixture required heating at 1150°C with agitation. Extra pure reagents containing determinants were used for calibrating standards instead of the red mud standard. The calibration curves of the 15 elements showed good linearity.
