Method development for the determination of cadmium, copper, lead, selenium and thallium in sediments by slurry sampling electrothermal vaporization inductively coupled plasma mass spectrometry and isotopic dilution calibration

A fast response cadmium-selective polymeric membrane electrode based on N,N′-(4-methyl-1,2-phenylene)diquinoline-2-carboxamide as a new neutral carrier

“…United States Environmental Protection Agency (EPA) has found cadmium to potentially cause the following health effects when people are exposed to it at levels above the minimum concentration level (MCL) for relatively short periods of time: nausea, vomiting, diarrhea, muscle cramps, salivation, sensory disturbances, liver injury, convulsions, shock and renal failure and in long-term cadmium has the potential to cause the following effects from a lifetime exposure at levels above the MCL: kidney, liver, bone and blood damage [4]. Recently, several techniques including; flame atomic absorption spectrometry (FAAS), electrothermal atomic absorption spectrometry (ETAAS), inductively coupled plasma mass spectrometry (ICP-MS) and atomic fluorescence spectrometry (AFS) [5][6][7][8][9][10][11][12] have been used for the determination of trace elements in different samples, but the wide utilization of these methods is limited by the expensive equipment. At the same Scheme 1.…”

Electroanalytical and naked eye determination of Cu2+ ion in various environmental samples using 5-amino-1,3,4-thiadiazole-2-thiol based Schiff bases

“…The CGE was also used for the determination of Cu 2+ ion in some medicinal plants 15 and perchloric acid, followed by controlled heating until the evolution of gases ceased. After digestion residue was removed by filtration and the filtrate was neutralized by NH 4 OH and the volume made up to 100 mL, Cu 2+ ion was determined with the help of the electrode by direct potentiometry method, the results tabulated in Table 6.…”

“…There are number of sophisticated techniques such as spectrophotometry [5,6], electro thermal atomic absorption spectrometry (ET-AAS) [7,8], adsorptive stripping voltammetry [9,10], flame atomic absorption spectroscopy (FAAS) [11,12], inductively coupled plasma-optical emission spectrometry (ICP-OES) [13,14] and inductively coupled plasma-mass spectrometry (ICP-MS) [15,16] have been used for the determination of copper.…”

Fabrication of novel coated pyrolytic graphite electrodes for the selective nano-level monitoring of Cd2+ ions in biological and environmental samples using polymeric membrane of newly synthesized macrocycle

“…Numerous analytical methods have been reported for the monitoring of Cd 2+ ion, such as, atomic fluorescence spectrometry (AFS) [10], electrothermal atomic absorption spectrometry (ETAAS) [11,12], flame atomic absorption spectrometry (FAAS) [13][14][15], the detection of radiolabel isotopes [16], electrochemical techniques [17], instrumental neutron activation analysis [18], inductively coupled plasma mass spectrometry (ICP-MS) [19] and diffusive gradient in thin films (DGT) [20]. However, these techniques have been employed successfully in the monitoring of cadmium but are not very convenient for the analysis of a large number of environmental samples as they demand of expertise, tedious sample preparation, time consuming and require good infrastructure.…”
