[ 1 ] - Extraction of Sulfathiazole from Urine Using Biosynthesized Magnetic Nanoparticles

The application of Pd/Fe3O4 nanoparticles (NPs) for the adsorption of sulfathiazole from urine samples prior to high performance liquid chromatography-ultraviolet detection was studied. Pd/Fe3O4 NPs were synthesized using plant extract. Possible impact parameters in the extraction process such as the magnetic adsorbents amount, extraction time, sample pH and desorption conditions were investiga...

[ 2 ] - Simultaneous Chloramphenicol and Florfenicol Determination by A Validated DLLME-HPLC-UV Method in Pasteurized Milk

The antibiotic residues in milk are a well-known serious problem and pose several health hazards to consumers. We have described a simple, rapid, and inexpensive DLLME-HPLC/UV technique for the extraction of chloramphenicol and florfenicol residues in milk samples. Under the optimum conditions, linearity of the method was observed over the range 0.02-0.85 µg/L with correlation coefficients > 0....

[ 3 ] - Extraction and Determination of Cyproheptadine in Human Urine by DLLME-HPLC Method

Novel dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography with photodiode array detection (HPLC-DAD) has been applied for the extraction and determination of cyproheptadine (CPH), an antihistamine, in human urine samples. In this method, 0.6 mL of acetonitrile (disperser solvent) containing 30 µL of carbon tetrachloride (extraction solvent) was ...

[ 7 ] - تأثیر سوش‌های مختلف از ساکارومایسس سرویزیه در کاهش میزان آفلاتوکسین‌های B1، B2، G1 و G2

ساکارومایسس سرویزیه ((Saccharomyces cerevisiae یکی از مهم‌ترین میکروارگانیسم‌های درگیر در تخمیر مواد غذایی در سرتاسر جهان است که گزارش‌های مختلفی از اثر این میکروارگانیسم بر جذب آفلاتوکسین‌ها منتشر شده است. هدف این مطالعه تأثیر سوش‌های مختلف ساکارومایسس سرویزیه بر کاهش آفلاتوکسین‌های B1، B2، G1 و G2 بود. برای این منظور سویه‌های استاندارد 5052 PTCC و 5269 PTCC ساکارومایسس سرویزیه تهیه و در محیط...
