Response Surface Methodology Optimization of Cobalt (II) and Lead (II) Removal from Aqueous Solution Using MWCNT-Fe3O4 Nanocomposite
The present investigation describes the evaluation of feasibility of MWCNT-Fe3O4 nanocomposite toward adsorptive removal of Co(II) and Pb(II) from aqueous solution in batch mode. The Fe3O4–MWCNT hybrid was prepared using a simple one-pot strategy via in situ growth of Fe3O4 magnetic nanoparticles onto the surface of the MWCNT...
متن کاملIn-situ preconcentration, and electrochemical sensing of zinc(II) and copper(II) based on ionic liquid mediated hollow fiber-modified pencil graphite electrode using response surface methodology
A single-use electrochemical sensor using ionic liquid mediated hollow fiber-graphite working electrode was fabricated for the first time. The screening tool was developed by coupling this electrode with differential pulse voltammetry (DPV) for in-situ pre-concentration and determination of Zn(II) and Cu(II). In our plot, porous polypropylene hollow fiber membrane was divided into pieces of 2 c...

کاتالیزورهای co-fe-resol/sio2و fe-mn-resol/sio2 با استفاده از روش ساده و ارزان قیمت همرسوبی تهیه شدند. از رزین پلیمری resol در فرآیند تهیه کاتالیزور استفاده شد.
Screening and Optimization of Microextraction of Pb(II) by Inductively Coupled Plasma-Atomic Emission Using Response Surface Methodology
Dispersive liquid–liquid microextraction (DLLME) combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was applied for the determination of lead in different environmental water samples. Ammonium pyrrolidine dithiocarbamate (APDC), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. The effective parameters, such...
