Investigators at Wuhan Polytechnic University Report Findings in Atomic Science

June 13, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Science. According to news originating from Wuhan, People's Republic of China, by NewsRx correspondents, research stated, "In this study, a novel method is presented for the preconcentration of trace silver using titanium dioxide nanotubes (TDNTs) as a new adsorption material packed into microcolumn prior to the determination by inductively coupled plasma mass spectrometry (ICP-MS). The adsorption and elution behaviors of silver ion studied on TDNTs were investigated systematically under dynamic conditions."

Our news journalists obtained a quote from the research from Wuhan Polytechnic University, "The effects of pH, sample flow rate and volume, elution solution, and interfering ions on the preconcentration and separation of the analytes were examined in detail. The adsorption capacity of TDNTs for Ag was found to be 8.5 mg g(-1). Under the optimum conditions, the detection limit (3 sigma) of this method was 0.021 ng mL(-1) for Ag, and the relative standard deviation was 4.5% (n=9, c=0.5 ng mL(-1)). This method was applied to the determination of trace Ag in biological samples with recoveries of 92.0-106%."

According to the news editors, the research concluded: "In order to validate this method, a certified reference material of GBW 07604 Poplar Leaves was analyzed, and the determined values were in good agreement with the certified values."
