Efficient simultaneous adsorption of heavy metal ions from solutions by modified graphene oxide with 3-aminopyrazole using central composite design modeling.
MWCNT-Py indicated a high adsorption capacity for phenol in comparison with MWCNT-COOH.
Abstract The bioactive compounds like rutin, naringin, and gallic acid have been separated from lemon peel by graphene oxide (GO). different influences such as pH values separation conditions were investigated. Moreover, the samples characterized Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, UV‐Vis high‐performance liquid chromatography. findings of chromatography revealed that adsorbed proportion rutin GO was more than naringin so 66.7%...
Abstract The removal of hazardous picric acid is great importance to making healthy and drinkable water. In this research, a nanocomposite (MWCNT‐EDTA‐CMC) based on carboxylated multiwall carbon nanotubes (MWCNT‐COOH) modified by carboxymethylcellulose (CMC) ethylenediamintetraacetic (EDTA) was prepared for adsorption from aqueous solutions. MWCNT‐EDTA‐CMC characterized Fourier transform infrared (FT‐IR), field‐emission scanning electron microscopy (FESEM), thermal gravimetric analysis...
Abstract The multi‐walled carbon nanotubes (MWCNTs) were first oxidized by nitric acid to form a MWCNT‐COOH. Then, it was modified with thiosemicarbazide produce MWCNT‐semi. Thus, these materials, MWCNTs, MWCNT‐COOH and MWCNT‐semi, have been used as efficient adsorbents for the removal of cadmium from aqueous solutions. influence variables including pH, concentration cadmium, amount contact time investigated batch method. kinetic studies carried out using different models such...
The carboxylated multiwall carbon nanotubes (MWCNT-COOH) and functionalized with isatin derivative (MWCNT-isatin) have been used as efficient adsorbents for the removal of lead (Pb) from aqueous solutions. influence variables including pH, concentration lead, amount contact time was investigated by batch method. adsorption ions solution modified MWCNTs studied kinetically using different kinetic models. data were fitted pseudo-first-order, pseudo-second-order, intra-particle diffusion...
In this research, carboxylated multiwalled carbon nanotubes (c-MWCNTs) were improved with 5-amino-3-(2-thienyl) pyrazole (p-MWCNTs) for adsorption of Cd2+ and As3+ from aqueous solutions. Field emission scanning electron microscopy, Fourier transform infrared spectra spectroscopy, energy-dispersive X-ray thermogravimetric analysis employed to characterize the p-MWCNTs. The central composite design inspected effects pH, adsorbent dose, initial metal ions concentration on process. Further,...
The chemical functionalization of carboxylated short multi-walled carbon nanotubes (Sh–MWCNT–COOH) by creatinine (Sh–MWCNT–amide) and later modification with aromatic aldehydes for producing 2-amino-5-arylidene-1-methyl-1H–imidazol-4(5H)-one (Sh–MWCNT–imidazols) via thermal microwave methods have been investigated. All the products were characterized Fourier transform infrared spectroscopy, Raman scanning electron microscope, elemental analysis, thermogravimetric derivative cellular...
Breast cancer cell lines MCF-10, MCF-7 and BT-474 expressing various levels of HER2 were examined for their response to treatment with sulforaphane (SLFN), metformin (MTFN), Nano-MTFN or combinations. Direct correlation was found between SLFN effect on death levels. Bioinformatic studies suggested the possibility additive co-effects fate by SLFN-MTFN co-treatment. This co-treatment specially + significantly affected survival cells killed more than other two. Cell sensitivity combination...
We reported a noticeable methodology for functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) using 1, 4-phenylendiamine and the latter modification by phenylisocyanate phenylisothiocyanate. All products were characterized FT-IR Raman spectroscopy, SEM, elemental analysis 1H NMR spectrum. The spectrum confirmed formation MWNT-amide, MWNT-urea MWNT-thiourea. Functionalization NH2, NHCO, NHCS NCO groups is very important due to increasing MWNT solubility creating active...
