Determination of aromatic amines in water samples by capillary electrophoresis with amperometric detection

Aromatic Amines Sources, Environmental Impact and Remediation

“…The technique uses fused silica capillaries under an electrical field, and separation occurs either solely on the basis of molecular weight and charge, electrophoretic mobility, or associated with differential solubilisation in surfactant micelles. Associated with preconcentration, pre-derivatisation or incapillary derivatisation techniques in order to overcome the problem of inherent low sensitivity, this method has shown potential for excellent separation efficiency (Asthana et al 2000;Cavallaro et al 1995;Sun et al 2009). …”

“…Taking advantage of the polar, ionisable nature of aromatic amines, capillary electrophoresis methods, both in the capillary zone electrophoresis and the micellar electrokinetic chromatography modes, have also been proposed for their fractionation in environmental samples (Martínez et al 2000;Oguri 2000;Ye and Huang 2007). A wide range of techniques have been applied for post-separation identification and quantification of CE peaks in aromatic amine analysis such as UV spectrophotometric, electrochemical (amperometric) and fluorescence detection (Asthana et al 2000;Sun et al 2009). Signal enhancement can be obtained through pre-or post-column derivatisation reactions with a chromophore or fluorophore (Asthana et al 2000).…”

Electroanalysis of Nitro and Amino Derivatives of Polycyclic Aromatic Hydrocarbons

“…Recently, capillary electrophoresis (CE) with amperometric detection has become a useful analytical tool for the determination of a variety of aromatic amines, as evidenced by many published papers, e.g., [222][223][224][225]. CE is relatively new separation technique compared to the traditional techniques such as HPLC or GC.…”

Cloud Point Extraction of Aromatic Amines From Environmental Water Samples Coupled With High-Performance Liquid Chromatography

“…[14][15][16] However, these methods are relatively expensive and consume large amounts of organic solvents or are tedious, time consuming, and not sensitive enough for trace analysis.…”
