Spectrophotometric Determination of Copper and Nickel in Marine Brown Algae after Preconcentration with Surfactant Assisted Dispersive Liquid-Liquid Microextraction
A simple, fast and effective pre-concentration method for the determination of Cu (copper) and Ni (nickel) was developed using a Surfactant Assisted Dispersive Liquid-Liquid Microextraction (SA-DLLME) coupled by UV-Vis spectrophotometry in marine brown algae. The complexing agent was 1- (2- pyridylazo) – 2 - naphthol (PAN).The effects of various experimental parameters in the extraction ste...
متن کاملPreconcentration of acrylamide with dispersive liquid-liquid microextraction based on solidification of floating organic drop prior to determination by HPLC
A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol w...
متن کاملUltrasound Assisted Emulsification Microextraction as a Simple Preconcentration Method for Determination of Atrazine in Environmental Samples
We represent an environmentally friendly sample of pre-treatment method, ultrasound assisted emulsification microextraction (USAEME) followed by gas chromatography nitrogen phosphorous detector (GC-NPD), to specify atrazine residues in environmental samples. Some parameters affecting the extraction efficiency such as the type and volume of the extraction solvent, emulsification time and additio...
متن کاملOptimized preconcentration of Imatinib using dispersive liquid-liquid microextraction coupled with HPLC-UV
Background: Imatinib is an antineoplastic agent acting as a tyrosine kinase inhibitor to treat cancer such as lymphoblastic leukemia. The dosage of the anticancer drugs plays a critical role in the survival of the patients. For this reason, the patient's plasma and urine samples should be monitored to obtain the necessary information regarding the toxicity of the drug. In this study, the applic...
متن کاملDetermination of Iron Species by Combination of Solvent Assisted-Dispersive Solid Phase Extraction and Spectrophotometry
A simple, rapid and sensitive solvent assisted-dispersive solid phase extraction method was developed for the extraction of iron(II) prior to its spectrophotometric determination. The Fe(II) reacted with 2,4,6-tris(2-pyridyl)-1,3,5-triazine, neutralized with sodium dodecyl sulfate and extracted onto the fine particles of benzophenone which were formed upon rapid injection of a mixture of benzop...
