the occurrence and fate of trace-level contamination of pharmaceuticals in the aquatic environment has been recognized as one of the emerging issues in environmental chemistry. the effluents of wastewater treatment plants, usually directly emitted to the environment, often contain the anti-inflammatory drug diclofenac. diclofenac was chosen because it is of high consumption; by background liter...

A sensitive and rapid method was developed for the determination of cAMP in Locusta migratoria manilensis Meyen by high-performance liquid chromatography with fluorescence detection. The cAMP was derivatized using chloroacetaldehyde and TBAS buffer/methanol was used as the mobile phase. A detection quantification of 40 fmol/ml could be achieved when using fluorescence detection. An HPLC-MS meth...

A sensitive and reproducible high-performance liquid chromatography-fluorescence method was developed and validated for quantitative determination of indoxyl sulfate in plasma using methyl paraben as an internal standard. The separation was carried out on an OSD-2 C18 Spherisorb column by isocratic elusion with sodium acetate buffer (pH 4.5) and acetonitrile (10:90, v/v) as the mobile phase. Th...

Interest in analytical methods for plant estrogens (phytoestrogens) has risen sharply in the past 10 years. In this review, we examine the existing analytical methods based on separations by gas–liquid chromatography, high-performance liquid chromatography and capillary electrophoresis in addition to methods of detection by ultraviolet absorption, fluorescence, electrochemical oxidation / reduc...
