In the present paper, the use of a modified electrochemical sensor for the determination of Pb2+ is described. The sensor is based on a carbon paste electrode modified with Nitro benzoil diphenyl methylene phosphorane, ...

The biosorption performance of Phlomis cancellata Bunge as inexpensive, abundant and easily available adsorbent for safranin cationic dye removal from aqueous system has been evaluated in a batch process, using response ...

A simple and efficient dispersive liquid-liquid microextraction (DLLME) method coupled with microvolume UV-vis spectrophotometry was developed for the determination of trace amounts of phosphate. This method is based on ...

Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important ...

Ocimum canum belongs to a genus of aromatic annual and perennial herbs and shrubs in the family of Lamiaceae. It is native to Africa and cultivated commonly for its culinary and medicinal value. In a previous study, we ...

A graphene oxide sorbent was modified with 8-hydroxyquinoline and used for solid phase extraction and selective determination of copper using flame atomic absorption spectrometry. In this method, a 5 mg of modified sorbent ...

So far, much research has been conducted to measure drug analytes both in pure form or simultaneously and different methodologies have been employed with their respective advantages and disadvantages. In this work, we have ...

The aim of the present study was to extract, preconcentrate and determine 17-β–Estradiol in water samples using a simple and efficient method; to this aim, salting-out-assisted liquid-liquid extraction and high-performance ...

The effects of environmental parameters, including solvent, pH and ionic strength on the fluorescence features of aflatoxin B1, B2, G1 and G2 were investigated. Fluorescence spectral characteristics such as fluorescence ...
