Congo red (CR) is a stable anionic diazo dye that causes allergic reactions with carcinogenic properties. The rapid removal of CR using cation-incorporated nanohydroxyapatite (pristine HAp: X (X = Fe, Ni, Zn, Co, and Ag)) was investigated. pristine cation ion-doped HAp adsorbents were coprecipitated subjected to hydrothermal ultrasound treatments subsequent microwave drying. dopant ions signifi...

Abstract Freshwater scarcity is a global threat to modern era of human society. Sorption-based atmospheric water harvesting (AWH) prospective provide fresh for remote water-stressed areas lacking in and electricity. Adsorbent material plays vital role such AWH systems. Here, we report solid adsorbent synthesized by impregnating hygroscopic salt lithium chloride (LiCl) into solidified activated ...

A comprehensive study on Phoenix dactylifera mediated green synthesis of ZnO, and different content (2%, 4%, 6%, 10%) Mn doped ZnO nanoparticles ([email protected]) were performed to evaluate the elimination dispersing acid dye methyl orange (MO) from aqueous solutions. The as-synthesized [email protected] adsorbents characterized by XRD, FT-IR, UV-VIS spectrophotometer, TEM, point zero charges...

Electrospun polyurethane fibers for removal of volatile organic compounds (VOC) from air with rapid VOC absorption and desorption have been developed. Polyurethanes based on 4,4-methylenebis(phenylisocyanate) (MDI) and aliphatic isophorone diisocyanate as the hard segments and butanediol and tetramethylene glycol as the soft segments were electrospun from their solutions in N,N-dimethylformamid...

Cellulose nanocomposites were synthesized and applied to the removal of Pb(II) from aqueous solution. The nanocomposite was characterized by FT-IR, XRD, SEM, TEM, BET analyses. Removal experiments carried out in laboratory scale then evaluated response surface methodology (RSM) with a Central-Composite Design. effects solution pH, contact tie, initial concentration, adsorbent dosage temperature...

Spongy graphene is a newly developed adsorbent of high performance for water treatment. Proper functionalization is an efficient approach to improve the adsorption capacity of graphene adsorbents. In this study, we prepared graphene oxide (GO), functionalized it with carboxyl groups to produce carboxylated GO (GO-COOH) dispersion, and lyophilized the GO-COOH dispersion to obtain the GO-COOH spo...

Colored effluents are one of the important environment pollution sources since they contain unused dye compounds which are toxic and less-biodegradable. In this work removal of Acid Red 14 and Acid Red 18 azo dyes was investigated by acidic treated pumice stone as an efficient adsorbent at various experimental conditions. Removal of dye increased with increase in contact time and initial dye co...

BACKGROUND/AIMS Cytokines play important roles in the pathophysiology of systemic inflammatory response syndrome (SIRS) and sepsis. Therefore, some effective measures to remove cytokines from the bloodstream could be effective in the treatment of SIRS and sepsis. The aim of this study was to evaluate the cytokine adsorptive property of various adsorbents for the purpose of the development of ne...

A study on the removal of arsenic from real life groundwater using iron-chitosan composites is presented. Removal of arsenic(III) and arsenic(V) was studied through adsorption at pH 7.0 under equilibrium and dynamic conditions. The equilibrium data were fitted to Langmuir adsorption models and the various model parameters were evaluated. The monolayer adsorption capacity from the Langmuir model...

In this paper, by analyzing the heat and mass transfer characteristics of dehumidification runner microelement channel a drinking water emergency extraction vehicle, mathematical model in intake process is established, influence parameters (adsorbent thickness, regeneration angle, rotation speed) air (treatment temperature/humidity, regenerated temperature/humidity) on mainly studied. Water exp...
