Ethylene glycol bisthioglycolate modified gold nanoparticles grafted Mn doped Fe3O4 nanoparticles (Au@Mn-Fe3O4 NPs) adsorbent was synthesized and applied for extraction and preconcentration of trace amounts of Ag+ and Pb2+ ions in artificial and natural saliva. The adsorbent was characterized by transmission electron microscopy (...

Abstract Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic,anti-infammatory and antipyretic actions. It is used to relieve mild to moderate pains. Solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . Poly allyl glycidyl ether/iminodiacetic acid-co-N, N-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

Dyes are widely used in various industries, since theirdirect discharge to nature can cause many biological and environmental problems. Some of these dyes are toxic, carcinogenic and can cause skin and eye irritation. There are various dye removal techniques, but Adsorption found to be very effective and cheap method among the all available dye removal methods. The purpose of this study was to ...

This work reports the preparation of molecularly imprinted polymer (MIP) particles for selective extraction and determination of silver ions from aqueous media. Various parameters were optimized, such as pH, time, concentration of sample and type of eluent for elution of silver from polymer. Also Interfering effect was investigated on the absorption of silver by molecularly imprinted polymer. A...

In this study, first of all, removal of dyestuffs from the wastewater ,which is biologically treated but colour removal is not achieved, was investigated by chemical coagulation (FeCl3, FeSO4 and Al2(SO4)3 coagulants), Fenton oxidation (different volume of peroxide and Fe+2) and ozone oxidation(1 gr/h ozone dose) methods. According to the experimental results, maximum color removal efficiencies...

In the present research, we report the results of a systematic study on the adsorption properties of folic acid (FA) over functionalized single-walled carbon nanotubes (SWCNTs) using the various factors, such as adsorbent dose, contact time, temperature, and initial FA concentration. Our results reveal that SWCNT is an excellent adsorbent for folic acid, with an adsorption percentage of up to 7...

An efficient and simple magnetic solid phase extraction based on the use of CoFe3O4 nanoparticles grafted multi-walled carbon nanotubes (MWCNTs) as adsorbent coupled with surfactant enhanced spectrofluorimetric detection...

The present study evaluates the suitability ofactivated carbon, prepared from Cane Papyrus, a plant that grows naturally and can be found quite easily, which serves as a biological sorbent for removal of  Cu2+ ions from aqueous solutions. Fourier transform infra-red analysis for the activated carbon, prepared fromCane Papyrus confirms the presence of amino (–NH), carbonyl (–C=O), and hydroxyl (...
