[ 1 ] - Synthesis Silver Nanoparticles by Recovery Silver from Anode Slime of Kerman Sarcheshmeh Cooper Complex
According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...
[ 2 ] - نانوفیبرهای الکتروریسی شده پلی اکریلونیتریل به عنوان پوشش جدید برای میکرو استخراج فاز جامد: کاربرد برای پیش تغلیظ و تعیین فتالات ها در نمونه های آب
چکیده در کار حاضر، برای اولین بار، نانو فیبر الکتروریسی شده پلی آکریلونیتریل به‌عنوان پوشش جدید در میکرو استخراج فاز جامد ((SPME و اندازه‌گیری فتالات‌ها از نمونه‌های آب معرفی شد. پارامترهای آزمایشگاهی مؤثر بر کارایی SPME، با استفاده از روش سطح پاسخ (RSM)، بر اساس طرح مرکب مرکزی (CCD) بهینه شدند. تحت شرایط بهینه، روش حاضر، دارای منحنی کالیبراسیون خطی در محدوده 1-100 ng/ml و ضریب همبستگی (r2) بیش...

[ 4 ] - A Developed Electromembrane Technique Based on Flat Electrospun Membrane Coupled with Gas-chromatography for the Determination of Phthalates in Different Water Samples
In this work, we successfully developed electromembrane extraction via preparation of an electrospun flat membrane based on device. The polyurethane-membrane was prepared by electrospinning method and used in EME. Affecting parameters on membrane preparation were optimized by Taguchi design. The developed method was used for extraction of phthalates as typical molecules and the proposed method ...
[ 5 ] - Desorption Kinetics of Heavy Metals (Lead, Zinc, and Nickel) Coexisted with Phenanthrene from a Natural High Buffering Soil
This work aims to investigate the competitive time-dependent desorption rate of heavy metals (lead, zinc, nickel) coexisting with phenanthrene from natural high buffering soil. Two non-ionic surfactants (Tween 80 and Brij 35) combined with disodium ethylene diamine tetraacetate salt (Na2-EDTA) were utilized as the reagents. The contaminants’ time-dependent desorption data was fitted with five k...
