A new fluorescent assay based on in situ ultrasound-assisted synthesis of carbon dots (CDs) as optical nanoprobes for the detection methylmercury has been developed. Application high-intensity sonication allows simultaneous performance CDs within analytical time scale and selective recognition target analyte. Microvolume fluorospectrometry is applied measurement fluorescence quenching caused by methylmercury. The uses low amounts organic precursors (fructose, poly(ethylene glycol), ethanol)...
A new cold vapor technique within the context of green chemistry is described for determination mercury in liquid samples following high-intensity ultrasonication. Volatile Hg evolved a sonoreactor without use chemical reducing agent carried to quartz cell kept at room temperature measurement atomic absorption. The mechanism involved lies reduction Hg(II) Hg(0) by gases formed upon sonication and subsequent volatilization due degassing effect caused cavitation phenomenon. Addition low...
