چکیده نانوذرات fe3o4 و نانو کامپوزیت cofe2o4 و مخلوطی از مایع یونی و نانوذرات fe3o4 (il-fe3o4 ) به روش همرسوبی تهیه گردید. میانگین اندازه و ریخت شناسی سطح نانوذرات به وسیله تکنیک های tem ، xrd و ftir تعیین شد. هر سه نانوذره برای حذف رنگ آلیزارین رد اس از محلول های آبی مورد استفاده قرار گرفت. مطالعات جذب سطحی آلیزارین رد اس تحت شرایط آزمایشگاهی متفاوت در سیستم ثابت انجام گرفت. نتایج آزمایش نشان...
Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression ...
cobitis keyvani is recently described from the sourhern caspian sea basin. limited information is available about morphological features of c. keyvani , therefore this study was conducted to provide osteological characteristics and cranial myology of this species. for this purpose, nine specimens of c. keyvani were collected from the talar river. the specimens were cleared and stained with aliz...
Spectrophotometric Assay of Noradrenaline in Pharmaceutical Formulation with Alizarin Red Sulphonate
In this study, the separation parameters in micellar electrokinetic chromatography (MEKC)-laser-induced fluorescence (LIF) were optimized for the separation of red and yellow historical dyes in 20 mM borate buffer with 20 mM sodium dodecyl sulfate (SDS). Separation conditions were optimized by changing pH, organic modifier (methanol and acetonitrile) concentrations and applied voltage. The mixt...
abstract in this work, fe3o4-graphene oxide nanocomposite (go-fe3o4) was prepared as effective absorbent for magnetic solid phase extraction (mspe) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (alizarin red s) and flame atomic absorption spectrometry (faas). the go-fe3o4 was characterized by scanni...
This research was aimed to study the adsorption of Alizarin Red S (ARS) dye using graphene oxide (GO) as an adsorbent compared with bare graphite powder (BGP). For optimum conditions, the effects of the initial concentration of ARS, solution pH, adsorbent dosage, and contact time were investigated in detail. The optimum conditions for this work were consisted of 350 mg/L initial concentration o...
