in this work, a new, simple and fast method for the solid phase extraction-spectrophotometric determination of phosphate using cetyltrimethyl ammonium bromide immobilized on alumina-coated magnetite nanoparticles (ctab@acmnps) has been developed. the determination of phosphate is based on the molybdenum blue method which was monitored at λmax of 810 nm. mnps and acmnps characterized by sem, vsm...

studies had shown that oxygenated compounds are important in food products. it seems that extraction methods had a profound influence on this factor. the goal of the present study is to investigate on flavor components of murcott mandarin obtained using cold-press and hydro distillation. in the last week of january 2012, at least 50 mature fruit were collected from many parts of the same trees....

an air–assisted liquid–liquid microextraction method for the extraction and preconcentration of trace amounts of some synthetic phenolic antioxidants in biological fluids followed by their determination by gas chromatography–flame ionization detection has been reported. in this method the target analytes are extracted into a few microliters of carbon tetrachloride (extraction solvent) from an a...
