摘要
A method of removing contaminants from slurry samples is set forth. The method includes the utilization of repeated pressurizing and depressurizing steps to disrupt solidified particles in solid-containing slurries thereby increasing decontamination efficiency. An expansion fluid is injected into the slurry sample sufficient to create microbubbles when the slurry sample is depressurized. The micro bubbles mechanically disrupt the solidified particles increasing contaminant exposure. The microbubbles also provide for increased interfacial regions where contaminants can accumulate at gas-liquid thin films that are in close proximity to and can be effectively removed using a suitable expansion fluid and optional decontamination agents.
