A fast and accurate microwave-assisted digestion method for arsenic determination in complex mining residues by flame atomic absorption spectrometry

Comparative study on open system digestion and microwave assisted digestion methods for metal determination in shrimp sludge compost

“…The first application of microwaves for sample preparation was reported in 1975 [27]. Since that time many microwave assisted dissolution methods have been developed to include a variety of sample matrices such as soil [28], fish [29], sediments [30], sludge [31][32][33][34] and biological and environmental samples [20,35]. Microwave digestion procedures are classified according to their operational modes; open vessel microwave assisted digestion, which is more prone to sample contamination, and susceptible to losses of volatile metals and closed (pressurised) vessel procedures, which are rapid and efficient digestion techniques.…”

Ranolazine-Functionalized Copper Nanoparticles as a Colorimetric Sensor for Trace Level Detection of As3+

“…Currently, the conventional methods employed for arsenic detection include atomic absorption spectrometry (AAS) [9,10], inductively coupled plasma (ICP) absorption spectrometry [11,12], and high-performance liquid chromatography (HPLC) [13]. These methods have proven to be complicated, expensive, with non-portable instruments, and time-consuming protocols, so they are neither easily available in developing countries nor capable for on-site field detection.…”

Detection of cadmium in soils using laser-induced breakdown spectroscopy combined with spatial confinement and resin enrichment

“…[7][8][9] These methods are widely used in soil for microelement analysis because of their high sensitivity and repeatability. 10 However, these methods require time-consuming sample preparation and cannot be applied in situ for rapid determination of pollution levels. 11,12 Researchers have proved that laser induced breakdown spectroscopy (LIBS) is a competitive spectroscopy technology based on plasma spectral analysis from samples.…”
