New Hydrazines Findings from Nankai University Described

June 13, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Hydrazines are discussed in a new report. According to news reporting out of Tianjin, People's Republic of China, by NewsRx editors, research stated, "A novel ceria (CeO2)-ordered mesoporous carbon (OMC) modified electrode for the sensitive amperometric determination of hydrazine was reported. CeO2-OMC composites were synthesized via a hydrothermal method at a relatively low temperature (180 C) and characterized by scanning electron microscopy (SEM), transmission electron microcopy (TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD)."

Our news journalists obtained a quote from the research from Nankai University, "The CeO2-OMC modified glassy carbon electrode was characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) and indicated good electrocatalytic effect to the oxidation of hydrazine. Under the optimized conditions, the present sensor could be used to measure hydrazine in wide linear range from 40 nM to 192 ?M (R(2)=0.999) with a low detection limit of 12 nM (S/N=3). Additionally, the sensor has been successfully applied to detect hydrazine in real water samples and the recoveries were between 98.2% and 105.6%."

According to the news editors, the research concluded: "Eventually, the sensor exhibited an excellent stability and reproducibility as a promising method for determination of hydrazine."
