Simultaneous atomic fluorescence spectrometric determination of traces of iron, cobalt and nickel after conversion to their carbonyls and gas-phase atomization by microwave-induced plasma

Mesoporous aluminosilica sensors for the visual removal and detection of Pd(II) and Cu(II) ions

“…A major advantage of aluminosilica nanosensors is their retaining functionality in terms of metal ion sensitivity after multiple reuse cycles [3][4][5][6][7][8][9][10][11][12][13][14][15]. The Cl À anion, which was used as the stripping agent at 0.1 mol/L concentration, could effectively remove Pd(II) and Cu(II) ions (i.e., decomplexation) (Tables S2 and S3).…”

“…With the common use of Cu(II) and Pd(II) targets ions in various industries and biologic treatments, numerous techniques have been developed for the detection of Cu(II) and Pd(II). Extensive techniques, such as extractive atomic absorption spectrometry [7], spectrophotometry [8], atomic absorption spectrometry [9], inductively coupled plasma-atomic emission spectroscopy [10], stripping voltammetry on a mercury drop [11], differential pulse anodic stripping voltammetry [12], X-ray fluorescence [13], and atomic fluorescence spectrometry, have been developed to detect Cu ions [14], leading to improvements in monitoring from the perspective of precision, accuracy, sensitivity, and selectivity. However, such procedures are also restricted by pre-concentration procedures and generation of organic wastes.…”

Detection of copper (II) in aqueous solution by immobilized urease obtained from agro-waste: Optimization of process variables

“…Nowadays, in the development of a new analytical procedure, the amount and toxicity of wastes are as important as any other analytical feature [8]. Several analytical techniques are actually available to analyze Cu 2+ concentration in environmental water with different matrices, such as atomic absorption spectrometry [9][10][11], inductively coupled plasma-atomic emission spectroscopy [12,13] stripping voltammetry on a mercury drop [14][15][16][17], differential pulse anodic stripping voltammetry [18], X-ray fluorescence [19], and atomic fluorescence spectrometry [20]. Besides the well-known advantages of these instrumental techniques (precision, accuracy, sensitivity, selectivity, etc.…”

Determination of Copper in Water, Vegetables, Foodstuffs and Pharmaceuticals by Direct and Derivative Spectrophotometry

“…Therefore, from this point of view, it is necessary to establish a rapid simple, sensitive and accurate procedure for the determination of copper concentration. Several techniques have been used for the determination of copper in different samples [11][12][13][14][15] . However these methods have the disadvantages that the operation of the instrumentation used, is complex and the price of the instrumentation is expensive compared with UV-visible spectrophotometry.…”
