[ 1 ] - اندازه‌گیری بقایای سموم کشاورزی ارگانوکلره در رودخانه‌های استان مازندران از طریق دستگاه ECD GC-پس از پیش‌تغلیظ به روش استخراج فاز جامد
سموم کشاورزی ارگانوکلره به علت خاصیت تجمعی، سرطان‌زایی و تأثیر در سیستم عصبی انسان اهمیت زیادی دارند. این سموم به علت طبیعت لیپوفیلیک، آبگریزی و سرعت پایین تخریب شیمیایی و بیولوژیکی، در بافت‌های بیولوژیکی جمع و وارد چرخۀ غذایی می‌شوند بنابراین، این آلاینده‌ها در حد غلظت نانو می‌توانند خطر جدی برای سلامت انسان محسوب شوند. از آنجا که رودخانه‌ها مهم‌ترین منبع آب آشامیدنی محسوب می‌شوند، بررسی کیفیت...
[ 2 ] - Amino Ethyl-Functionalized SBA-15: A Promising Adsorbent for Anionic and Cationic Dyes Removal
Batch Adsorption of Acid Red 37 (AR37) and Basic Orange 2 (BO2) on amino ethyl-functionalized SBA-15 have been studied. SBA-15 was synthesized and functionalized according to the procedure in the literature. Amino ethyl-functionalized SBA-15 showed the BET surface area 520 m2/g and pore diameter 7.02 nm, based on adsorption-desorption of N2. SEM image shows lengthy fib...
[ 3 ] - Fluorene Functionalized Nanoporous SBA-15 as a Novel Adsorbent for Fast and Efficient Removal of Acid Dyes
SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...
[ 4 ] - Efficient Removal of Methylene Blue from Aqueous Solution by Adsorption on Cerium Vanadate Nanoparticles
Cerium vanadate nanoparticles (CVNPs) were used as a solid phase adsorbent for removing methylene blue (MB) from aqueous media. The nanoparticles were obtained through a direct precipitation procedure in aqueous solutions, and were characterized by X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). The results proved the product to comprise 25-45 nm particles. Bat...

[ 6 ] - Application of Copper Vanadate Nanoparticles for Removal of Methylene Blue from Aqueous Solution: Kinetics, Equilibrium, and Thermodynamic Studies
Copper vanadate nanoparticles were synthesized by a simple coprecipitation method in an aqueous medium and the products were used as adsorbents for eliminating methylene blue (MB) from water. The structure and morphology of the produced nanoparticles were evaluated through X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) analysis. The results...
[ 7 ] - Efficient removal of reactive Blue-19 from textile wastewater by adsorption on methyl Imidazolium modified LUS-1 and MCM-48 nanoporous
In this study, N-methyl-N'propyltrimethoxysilylimidazoliummodified LUS-1 and MCM-48 nonoporous materials were prepared and employed as adsorbent for removing Reactive Blue-19 from aqueous solutions.LUS-1 and MCM-48 were made based on the previous procedure and modified with N-methyl-N'propyltrimethoxysilylimidazolium chloride. XRD analyses did not show any lattice alteration between modified an...
