Membranes and Sorbents

2018
For continuous renal replacement therapy (CRRT), the extracorporeal filter provides solute depuration, fluid removal, and control of electrolyte and acid-base balance in critically ill patients with acute kidney injury (AKI). The membranes comprising CRRT filters are almost exclusively based on hollow fiber designs and, while adapted from the chronic ...

Sorbents

2009
Abstract Chapter 23 discusses sorbents, including removal of target substances by sorbent in sepsis, selectivity of sorbent used for the removal of target substance, efficiency of adsorption, and typical modalities of utilization of sorbents.

History and Development of Sorbents and Requirements for Sorbent Materials

2023
The history of sorbents is about 2 centuries long. It is important to analyze and report the progress of science in this field, understand how modern hemoadsorption takes place, and appreciate how new devices have been designed and manufactured. It is also important to describe the nature, the structure, and the composition of sorbent materials and ...

Hierarchically Imprinted Sorbents

Chemistry, 2001
A double imprinting methodology was developed to synthesize novel materials with hierarchical structures. On the microporous level (1-3 A), metal ions served as template. On the mesoporous level (diameters of 25-40 A), micellar structures produced by self-assembly of surfactant molecules were used as templates. Removal of both metal ions and surfactant

Sorbents

Abstract Sorbents, material used to adsorb solutes from blood or plasma, use hemoadsorption selectively (e.g., endotoxin) or in a broad-spectrum fashion. An example is endotoxin, a lipopolysaccharide (LPS) outer membrane molecule essential for virtually all gram-negative bacteria.

Microextraction by Packed Sorbent

Bioanalysis, 2015
Microextraction by packed sorbent (MEPS) is a miniaturized form of SPE. MEPS can handle small sample volumes and be connected on-line with LC or GC without any modifications. In addition, the MEPS sorbent bed is integrated into an injection syringe and can be used for more than 100 extractions. The key aspect of MEPS is that the solvent volume used for

Sorbent Hemodialysis: Clinical Experience With New Sorbent Cartridges and Hemodialyzers

ASAIO Journal, 2008
To recycle spent dialysate, a sorbent hemodialyzer uses a purification cartridge, adapted from water reclamation systems originally designed for the aerospace program. Increasing interest in home hemodialysis has driven a renewed examination of sorbent dialyzer technology, resulting in the development of a modern sorbent hemodialyzer and an array of ...

Sorbent Suspensions vs. Sorbent Columns for Extracorporeal Detoxification in Hepatic Failure

Therapeutic Apheresis and Dialysis, 2006
Abstract:  Hepatic failure is a significant medical problem which has been unsuccessfully treated by hemodialysis. However, similar therapies using recirculated dialysate regenerated by sorbents in place of single‐pass dialysate have been beneficial in treating acute‐on‐chronic liver failure.
