Graphene oxide-based dispersive-solid phase extraction for preconcentration and determination of ampicillin sodium and clindamycin hydrochloride antibiotics in environmental water samples followed by HPLC-UV detection
In the present study, a reusable graphene oxide (GO) based dispersive-solid phase extraction (d-SPE) was synthesized and applied for the analysis of trace ampicillin sodium (AMP) and clindamycin hydrochloride (CLI) in water samples followed by high performance liquid chromatography-UV detection (HPLC-UV). Batch experiments were conducted to investigate the effects of pH and volume of the sample...

متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Hair analysis for abused drugs by capillary zone electrophoresis with field-amplified sample stacking.
The present paper describes the methodological optimisation and validation of a capillary zone electrophoresis method for the determination of morphine, cocaine and 3,4-methylenedioxymethamphetamine (MDMA) in hair, with injection based on field-amplified sample stacking. Diode array UV absorption detection was used to improve analytical selectivity and identification power. Analytical condition...
متن کاملThe Electrochemical Sensor for Selective Solid Phase Extraction of Pseudoephedrine Hydrochloride in a Real Sample
In the current study, a new technique was developed for quantification and qualification of pseudoephedrine hydrochloride (PSE) in a real sample, which was based on electrochemical sensors and molecular imprinted polymer (MIP). The carbon paste electrode (CPE) was modified and optimized by a different ratio of MIP. MIP/CPE was used as the extraction and working electrod...
