This study was focused on nettle ash as an alternative adsorbent for the removal of nickel (II) and cadmium (II) from wastewater. Batch experiments were conducted to determine the factors affecting adsorption of nickel (II) and cadmium (II). The adsorption process is affected by various parameters such as contact time, solution pH and adsorbent dose. The optimum pH required for maximum adsorpti...

Endosulfan has been applied to control numerous insects in a variety of food and non-food crops. Limited information is available on dynamics of this pesticide in the soil. The objective of this research was to determine the adsorption-desorption behavior of the alpha (alpha) and beta (beta) endosulfan in a Vertisol from the southeast region of Turkey, where cotton is the main crop in the large...

A type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. The aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. The hypercross-linked fiber adsorbent possesses a principall...

The IR spectra of adsorbed CO and NO probe molecules were used to characterize the coordination chemistry of Fe(2+) ions in solution ion exchanged Fe,H/SSZ-13 zeolites. The effects of Fe ion exchange levels, as well as the sample pre-treatment conditions, on the adsorption of these probe molecules were investigated. The ion exchange levels (in the range of the study) did not affect significantl...

graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove rhodamine b (rb) and malachite green (mg), two organic dyes, from aqueous solutions. adsorption kinetics of rb and mg onto graphene and adsorption capacity of the adsorbent were studied. also the effects of parameters, including ph, contact time, temperature, and adsorbent dosage we...

Husk of tur dal (Cajanus cajan) was investigated as a new biosorbent for the removal of Fe (III) and Cr (VI) ions from aqueous solutions. Parameters like agitation time, adsorbent dosage and pH were studied at different initial Fe (III) and Cr (VI) concentrations. The biosorptive capacity of the Tur dal husk was dependent on the pH of the chromium and iron solution, with pH 2 and 2.5 respective...

the present study was carried out to investigate the potential of carboxylate group functionalized multi-walled carbon nanotubes (mwcnt−cooh) adsorbent for the removal of methyl orange (mo) textile dye from aqueous solutions. the effects of ph, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚k was fixed at 25 min. the effect of te...

This research determined the adsorption performance of Florisil® impregnated with trihexyl(tetradecyl)phosphonium chloride (Cyphos IL-101) in the process of Cs+ removal from aqueous solutions. The obtained Florisil® impregnated with the studied ionic liquid was characterized through energy dispersive X-ray analysis and Fourier transform infrared spectroscopy in order to verify that the impregna...
