Researchers from Science University of Malaysia Report Details of New Studies and Findings in the Area of Solvents

February 28, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Solvents. According to news reporting originating in Pulau Pinang, Malaysia, by NewsRx journalists, research stated, "A cloud point extraction (CPE) process using non-ionic surfactant (DC193C) to extract selected paraben compounds from water samples was investigated using reversed phase high performance liquid chromatography (RP-HPLC). The CPE process with the presence of -cyclodextrin (CD) functionalized ionic liquid as a modifier (CPE-DC193C-CD-IL) is a new extraction technique that has been applied on the optimization of parameters, i.e., pH, CD-IL concentration and phase volume ratio."

The news reporters obtained a quote from the research from the Science University of Malaysia, "This CPE-DC193C-CD-IL method is facilitated at 30 degrees C, showing great losses of water content in the surfactant-rich phase, resulting in a high pre-concentration factor and high distribution coefficient. The developed method CPE-DC193C-CD-IL did show enhanced properties compared to the CPE method without the modifier (CPE-DC193C). The developed method of CPE-DC193C-CD-IL gives an excellent performance on the detection of parabens from water samples with the limit of detection falling in the range of 0.013-0.038 g mL(-1)."

According to the news reporters, the research concluded: "Finally, the inclusion complex formation, hydrogen bonding, and - interaction between the CD-IL, benzyl paraben (ArP), and DC 193C were proven using H-1 NMR and 2D NOESY spectroscopy."
