New tecniques of coal materials pretreatment for total reflection X-Ray fluorescence analysis

Abstract

The modern methods of determination of coal materials element composition are considered. The approaches to solving this problem with Total Reflection X-Ray Fluorescence (TXRF) method are suggested. The slurry preparation is chosen as a method for express sample pretreatment. The slurry preparation conditions are determined: sample mass, surfactant type and concentration, internal standard. The estimation of slurries stability and practical guidelines for its application in TXRF are given.
Key words: Total Reflection X-Ray Fluorescence, sample pretreatment, coal, coke.
