Some green approaches in atomic absorption spectrometry. The last 10 years

Green direct ultrasonic slurry sampling and electrothermal atomic absorption spectrometry method for metal analysis of solid plastics samples

“…15 As a result of the above, there is an increasing need to develop methods based on the principles of green analytical chemistry (GAC). 16 From the GAC perspective, direct non-destructive analytical methods such as X-ray uorescence spectroscopy (XRF), 17 neutron activation analysis (NAA), 18 or even the destructive direct solid sampling (DSS) technique, 19,20 can be used for the metal analysis of solid plastics samples; these do not require any treatment of the solid sample. However, these methods have a problem with the representativeness of the analysed sample, inhomogeneity of the samples, matrix effects, calibration standards and availability of certied reference materials (CRMs).…”

A fluorescent probe based on an enhanced ICT effect for Hg2+ detection and cell imaging

“…[15][16][17][18][19][20][21] When Hg 2+ reacts with the probe, it will signicantly change the uorescence emission of the probe, thus achieving the purpose of detecting Hg 2+ . Compared with conventional detection methods (such as atomic absorption spectrometry [22][23][24][25] ), the advantage of the uorescent probe is that the evaluation of the analyte can be done without the aid of complex experimental instruments, which is useful in environments with relatively complex experimental conditions. [26][27][28][29][30][31][32][33][34] In addition, conventional assays usually require killing the tissue when detecting the analyte content in biological tissues, whereas some uorescent probes can perform uorescence imaging without destroying the biological tissue due to their high biocompatibility.…”
