Analyzing REEs from Power Plant Fly Ash – How to Avoid Common Pitfalls in Sample Pretreatment and ICP Analysis

Introduction

The criticality of rare earth elements (REEs) has recently driven us to look closer at possible secondary sources of REEs. In this on-demand webinar, Siiri Perämäki, Ph.D, from the University of Jyväskylä takes a close look at how to accurately determine the concentration of rare earth elements in coal and bio-based fly ashes and discusses some common pitfalls in sample pre-treatment and analysis using ICP-MS and ICP-OES techniques.

Objectives include:

• How to efficiently dissolve fly ash samples for REE analysis
• Examples of common interferences faced in REE analysis using ICP-OES
• Some practical solutions to correct for matrix and spectral interferences
• How ICP-MS can solve these problems in REE analysis
