Phragmites australis: An alternative biosorbent for basic dye removal
(Elsevier Science Bv, 2016)
This study is aimed at investigating the removal of methylene blue (MB) from aqueous solutions using a reed species, Phrag-mites australis as an adsorbent. P. australis was modified by means of a chemical treatment, assuring ...
Removal of various anionic dyes using sodium alginate/poly(N-vinyl-2-pyrrolidone) blend hydrogel beads
(Springer, 2015)
In this study, novel blend hydrogel beads were prepared for the use in removal of anionic textile dyes due to their hazardous impact to nature. Sodium alginate and sodium alginate/poly(N-vinyl-2-pyrrolidone) beads were ...
Reversible immobilization of glucose oxidase on polyaniline grafted polyacrylonitrile conductive composite membrane
(Elsevier Sci Ltd, 2010)
Polyacrylonitrile membrane surfaces were modified with chemical polymerization of conductive polyaniline. The effect of aniline concentration on the grafting efficiency was investigated As the amount of grafted PANI increased ...
Surface modification of polyacrylonitrile film by anchoring conductive polyaniline and determination of uricase adsorption capacity and activity
(Elsevier, 2010)
Polyacrylonitrile (PAN) films were modified with chemical polymerization of conductive polyaniline (PANI) in the presence of potassium dichromate as an oxidizing agent. The effect of aniline concentration on the grafting ...
Removal of Benzidine-based Azo Dye from Aqueous Solution Using Amide and Amine-functionalized Poly(ethylene terephthalate) Fibers
(Korean Fiber Soc, 2010)
In this study, amide and amine groups bound to poly(ethylene terephthalate) fibers are used to remove the colored toxic Congo red dye from aqueous solution. The effects of process variables like pH, contact time, graft ...
Studies on Selective Uptake Behavior of Hg(II) and Pb(II) by Functionalized Poly(Ethylene Terephthalate) Fiber with 4-Vinyl Pyridine/2-Hydroxyethylmethacrylate
(Springer International Publishing Ag, 2010)
The adsorption behavior of 4-vinyl pyridine and 2-hydroxyethylmethacrylate grafted poly(ethylene terephthalate) fiber toward the Hg(II) and Pb(II) ions in aqueous solutions was studied by a batch equilibration technique. ...
Removing of Congo red from aqueous solution by 2-hydroxyethyl methacrylate-g-poly(ethylene terephthalate) fibers
(Springer, 2019)
Grafting of 2-hydroxyethyl methacrylate (HEMA) on poly(ethylene terephthalate) (PET) fibers was carried out via free-radical polymerization technique using benzoyl peroxide as initiator. The obtained copolymers were examined ...
Highly porous NiO/poly(DVB)HIPE nanocomposites for asphaltene removal: synthesis, kinetics, and thermodynamic studies
(Springer, 2019)
Asphaltene precipitation is one of the most important problems of the petroleum industry. Asphaltene collapses during petroleum processing and extraction from the well, blocking the pipes and causing many problems. For ...
Elimination of carcinogenic bromate ions from aqueous environment with 4-vinyl pyridine-g-poly(ethylene terephthalate) fibers
(Springer Heidelberg, 2019)
In this study, poly(ethylene terephthalate) fibers grafted with 4-vinyl pyridine (PET-g-4VP) was synthesized with using a radical polymerization method and its removal capacity for bromate ions in the aqueous solution was ...
Removal of Common Heavy Metals from Aqueous Solutions by Waste Salvadora persica L. Branches (Miswak)
(Springer International Publishing Ag, 2014)
The adsorption ability of miswak (Salvadora persica L.) waste was investigated for the removal of common heavy metals; Pb(II), Cu(II), Ni(E) and Cd(II), from aqueous systems. The miswak mainly consists of saponins, tannins, ...
