Polypropylene-based microextraction method for determination of fluoxetine in human urine samples
, Article Analytical Letters ; Volume 45, Issue 13 , 2012 , Pages 1777-1785 ; 00032719 (ISSN) ; Marzancola, M. G ; Es'haghi, A ; Sharif University of Technology

Abstract
A polypropylene (PP) sheet was successfully applied as an extracting medium for trace enrichment of fluoxetine (FLX) from urine samples, followed by high performance liquid chromatography-fluorescence detection (HPLC-FD). The extraction medium was a square, 1 × 1 cm2 piece of polypropylene membrane sheet that was conditioned in methanol. The extraction process was conveniently carried out using a 5 mL urine sample. After extraction, the PP sheet was withdrawn and transferred to a glass vial for performing the desorption process using 210 μL organic solvent. After complete drying, the residue was dissolved in 50 μL of methanol and an aliquot of 20 μL was, finally, injected into the HPLC...
A Polypropylene-Based Microextraction Method Coupled with HPLC-FD for Determination of Fluoxetine in Human
, M.Sc. Thesis Sharif University of Technology ; Bagheri, Habib (Supervisor)
Abstract
Considering principles of both micro-solid phase extraction (µ-SPE) and stir-bar sorptive extraction (SBSE) techniques, in this study a microextraction technique was developed using a polypropylene sheet as extracting device for isolation of fluoxetine from biological samples. Being rather inexpensive and simple to prepare extracting device, elimination of time consuming sorbent synthesis step and memory effect are some of the advantages of the proposed method. The extraction process was performed using a polypropylene sheet as extracting device. Solvent desorption was performed in a microvial and then extractant was injected into HPLC system. The effect of various parameters including pH,...
Fe3O4 Nano Particle-Based Magnetic Solid Phase Extraction of Oxadiargy1 and Fluoxetine from Aquatic and Biological Media
, M.Sc. Thesis Sharif University of Technology ; Bagheri, Habib (Supervisor)
Abstract
In this study new magnetic solid phase extraction (MSPE) methods based on Fe3O4 magnetic nanoparticles (NPs) for extraction and preconcentration of oxadiargyl and fuoxetine from aqueous and biological samples were developed. In the first work, Fe3O4 NPs was successfully used as a magnetic nano-sorbent in magnetic micro-solid phase extraction (M-µ-SPE) of oxadiargyl, a newly used pesticide, from environmental water samples prior to gas chromatography-mass spectrometry determination. Oxadiargyl in mild acidic condition has tendency to be adsorbed on Fe3O4 NPs surfaces. Most important parameters that affect the extraction efficiency were also studied. Under optimized condition, the proposed...
QSRR study of psychiatric drugs using classification and regression trees combined with adaptive neuro-fuzzy inference system

Abstract
A new Quantitative Structure-Retention Relationship (QSRR) approach was carried out for prediction of gas-liquid retention times of 124 psychiatric drugs in whole blood on fused-silica capillary column coated with crosslinked methylsilicone with nitrogen-phosphorus detection. After screening the descriptors, a total of 699 topological, geometric, and electronic descriptors (zero-to three-dimensional) representing various structural characteristics were calculated for each molecule in the dataset. Combined method of Classification and Regression Tree (CART) as a feature selection method for the extraction of four relevant descriptors and Adaptive Neuro-Fuzzy Inference System (ANFIS) as a...
The Nanocomposite Material-based Sorbents for Analysis of Environmental and Biological Samples
, Ph.D. Dissertation Sharif University of Technology ; Bagheri, Habib (Supervisor)
Abstract
This thesis contains two major sections. The first section is dealing with the preparation of conductive polymers-based sorbents while the second section is mostly focused on the synthesizing nanocomposites by electrospinning. All the prepared sorbents and nanofibers have been utilized to isolate some organic compounds in environmental and biological samples. Section I:In the first chapter, an unbreakable solid phase microextraction fiber coating based on aniline-silica nanocomposite was electrodeposited on a stainless steel wire. The electropolymerization process was carried out at a constant deposition potential, applied to the corresponding aqueous electrolyte containing aniline and...
Extraction of fluoxetine from aquatic and urine samples using sodium dodecyl sulfate-coated iron oxide magnetic nanoparticles followed by spectrofluorimetric determination
, Article Analytica Chimica Acta ; Volume 692, Issue 1-2 , 2011 , Pages 80-84 ; 00032670 (ISSN) ; Zandi, O ; Aghakhani, A ; Sharif University of Technology
Abstract
A new method based on the combination of magnetic solid phase extraction (MSPE) and spectrofluorimetric determination was developed for isolation and preconcentration of fluoxetine form aquatic and biological samples using sodium dodecyl sulfate (SDS) coated Fe3O4 nanoparticles (NPs) as a sorbent. The unique properties of Fe3O4 NPs including high surface area and strong magnetism were utilized effectively in the MSPE process. Effect of different parameters influencing the extraction efficiency of fluoxetine including the amount of Fe3O4 and SDS, pH value, sample volume, extraction time, desorption solvent and time were optimized. Under optimized condition, the method was successfully applied...
