Separation of coal fly ash using continuous steric field-flow fractionation

Separation of coal fly ash using continuous steric field-flow fractionation

The principles and advantages of continuous steric field-flow fractionation for the size separation of complex environmental samples are reviewed. Following prefractionation according to magnetic and density properties, this approach was successfully applied to four well-characterized flyash samples...

Zusammenfassung:The principles and advantages of continuous steric field-flow fractionation for the size separation of complex environmental samples are reviewed. Following prefractionation according to magnetic and density properties, this approach was successfully applied to four well-characterized flyash samples. The mode size of ash particles in different fractions coincided with theoretical predictions. Fractionation was shown to be best for samples that were prefractionated.
