ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...
15 صفحه اولChemically-Modified Activated Carbon with L-Arginine for Selective Solid Phase Extraction and Preconcentration of Metal Ions
In this study, a new sorbent of chemically-modified activated carbon with L-arginine (AC-Arg) has been produced as solid-phase extraction, to trace Zn(II) and Cd(II) ions in real samples, including soil and water samples, by Flame Atomic Absorption Spectrometry (FAAS). Once the surface coverage value is determined, the surface modification has been investigated and assessed, while having em...
متن کاملActivated Carbon from Olive Wastes as an Adsorbent for Chromium Ions Removal
Adsorption of Chromium ions (VI) and (III) in aqueous solution was investigated using activated carbon prepared from olive wastes, by one step physical activation with steam. After adsorbent material characterization using adsorption capacity of methylene blue, iodine and phenol, BET surface area, Fourier Transform InfraRed (FT-IR) spectroscopy, pHpzc, surface functions based on the Boehm m...
متن کاملExtraction and preconcentration of Pb(II) from water and soil samples using modified activated carbon
In this work, a new extractant was prepared by immobilizing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, (5-Br-PADAP), on the activated carbon and applied to extraction of Pb(II) prior to determination by flame atomic absorption spectrometry. It was confirmed by FT- IR analysis. The metal ion was retained on the 0.05 g of the sorbent in the pH range 6-8, and then eluted with 5 mL of 0....
متن کاملComparison of Modified Palladium Nanoparticles and Homemade Activated Carbon Derived from Medlar for Solid Phase Extraction of Metal Ions Prior to Their Flame Atomic Absorption Spectrometry Determination
This study focus on the preparation of two supports including activated carbon derived from medlar and Palladium nanoparticles loaded on activated carbon (Pd-NP-AC). Subsequently, both adsorbent modified with a novel Schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. The method is based on c...
