Abstract: A sorbent device based on a porous membrane bag (e.g., porous propylene membrane bag) encapsulated alkaline-modified zeolite (e.g., alkaline-treated USY zeolite). A process for removing heavy metals, such as Cd(II), Cr(III), and Pb(II) from an aqueous solution or an industrial wastewater samples with the sorbent device is provided. A method for preparing the alkaline-modified zeolite is also described.

Abstract: A membrane-based inverted liquid-liquid extraction method for extracting an analyte from an unsupported aqueous liquid sample includes sealing the unsupported aqueous liquid sample in a porous membrane bag, immersing the porous membrane bag in an organic solvent, and extracting the analyte from the unsupported aqueous liquid sample to produce an extract within the organic solvent. The unsupported aqueous liquid sample is immiscible with the organic solvent. The porous membrane bag does not contain a solid sorbent.

Abstract: A method for extracting an analyte from a solid sample is described. The sample is sealed in a porous membrane bag, which is sonicated in an organic solvent. An extract of the analyte forms in the bag and diffuses into the organic solvent. The organic solvent containing the extract may then be concentrated and analyzed for an analyte with gas chromatography-mass spectrometry. The method does not the use of a solid sorbent material, and does not require a step of centrifuging or filtering.
