Ion-Exchange Chromatography

Ion-Exchange Chromatography

Ion-exchange chromatography, or IEC, is a technique for separating ions based on their affinity for the stationary phase. The stationary phase is a cross-linked polymer resin with covalently attached ionic functional groups. The functional groups can be either positively charged (cation exchangers) or negatively charged (anion exchangers). A cation exchanger consists of a polymeric anion and active cations, while an anion exchanger is a polymeric cation with active anions. The choice of...

Capillary Electrophoresis: Applications

Capillary Electrophoresis: Applications

Capillary electrophoretic separations offer various modes, each with unique applications. These modes include capillary zone electrophoresis, capillary gel electrophoresis, capillary array electrophoresis, capillary isoelectric focusing, capillary isotachophoresis, micellar electrokinetic chromatography, and capillary electrochromatography.
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...

Extraction: Advanced Methods

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is formed in...

Dialysis

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Area of Science:

Environmental Chemistry
Analytical Chemistry
Materials Science

Background:

Environmental water analysis requires efficient sample pretreatment.
Conventional methods like solid-phase extraction (SPE) can be time-consuming and resource-intensive.
Miniaturized techniques offer advantages in speed and reduced solvent consumption.

Purpose of the Study:

To develop a new miniaturized sample pretreatment and preconcentration technique for environmental water samples.
To utilize a mixed matrix membrane (MMM) incorporating octadecyl (C18) particles for the extraction of non-steroidal anti-inflammatory drugs (NSAIDs).
To evaluate the performance of the C18-MMM for the analysis of NSAIDs compared to conventional SPE.

Main Methods:

A mixed matrix membrane (C18-MMM) was fabricated by dispersing C18 particles in a cellulose triacetate matrix.
A small piece of C18-MMM was used to adsorb NSAIDs from water samples.
Adsorbed NSAIDs were desorbed using methanol and ultrasonication.
Analysis was performed using high-performance liquid chromatography (HPLC).

Main Results:

The C18-MMM demonstrated high affinity for NSAIDs in tap and river water.
Relative recoveries for NSAIDs ranged from 92% to 100%.
Good reproducibility was achieved with relative standard deviations between 1.1% and 5.5% (n=9).

Conclusions:

The developed C18-MMM is a simple, miniaturized, and effective technique for NSAID extraction from environmental water.
The performance of the C18-MMM is comparable to conventional C18 SPE cartridges.
This method offers a promising alternative for routine environmental monitoring of NSAIDs.
