The procedure outlined describes an extremely sensitive and accurate method for the determination of mercury down to 1.0 ppb in solution. This procedure has been applied to nickel and cobalt metal as well
Here the authors report the first worldwide reconnaissance study of the presence and occurrence of pesticides in fruit-based soft drinks. While there are strict regulations and exhaustive controls for pesticides in fruits, vegetables, and drinking water, scarce attention has been paid to highly consumed derivate products, which may contain these commodities as ingredients.
Trace determination of fluoroquinolone antibacterial agents in urban wastewater by solid-phase extraction & liquid chromatograph
Fluoroquinolones (FQs) are among the most important antibacterial agents (synthetic antibiotics) used in human and veterinary medicine. An analytical method based on reversed-phase liquid chromatography with fluorescence detection was developed and validated for the simultaneous determination of nine FQs and the quinolone pipemidic acid in urban wastewater.
