“…Kong et al investigated the Cr(VI) ion adsorption behavior of DMAEMA-grafted PP (PP-g-PDMAEMA) fibers quaternized with bromoalkanes of different alkyl chain lengths [21]. The adsorption capacity of the quaternized PP-g-PDMAEMA (PP-g-QPDMAEMA) fibers were higher than that of the original PP-g-PDMAEMA fiber and the PP-g-QPDMAEMA fiber prepared with bromobutane had the maximum adsorption capacity.…”

A novel polymeric adsorbent for hexavalent chromium (Cr(VI)) ions was developed by photografting 2-(dimethylamino)ethyl methacrylate (DMAEMA) to a polyethylene (PE) mesh substrate. The DMAEMA-grafted PE (PE-g-PDMAEMA) meshes obtained were quaternized with iodoalkanes of different alkyl chain lengths. The grafting of DMAEMA and subsequent quaternization of dimethylamino groups were characterized by the FT-IR measurements. The Cr(VI) ion adsorption capacity at pH 3.0 and 30°C had the maximum value at the grafted amount of 2.6 mmol/g and the adsorption behavior obeyed the mechanism of the pseudo-second order kinetic model and well expressed by Langmuir isotherm. This can suggest that the adsorption occurs through an electrostatic interaction between protonated dimethylamino groups and hydrochromate ions. Cr(VI) ions were successfully desorbed in eluents such as NaOH, NaCl, and NH4Cl. When the PEg -PDAMEMA meshes were quaternized with the iodoalkanes, the adsorption capacity increased and the maximum adsorption ratio was obtained for the PEg -PDMAEMA mesh quaternized with iodoheptane. This value was about 1.83 times higher than the original PEg -PDAMEMA mesh. The results obtained in this study emphasize that the PEg -PDMAEMA meshes and their quaternized products can be applied as an adsorbent for Cr(VI) ions.

“…Thermodynamic study of an adsorption process can reveal the feasibility and spontaneous nature of the adsorption process [1]. The free energy changes (DG o , kJ mol À1 ), standard enthalpy changes (DH o , kJ mol À1 ) and the entropy changes (DS o , J mol À1 K À1 ) are three basic thermodynamic parameters associated with the adsorption process.…”

“…Heavy metals such as cadmium, chromium, copper, lead and mercury are highly dangerous to human beings as well as environment, even at low concentration levels in water [13]. As one of the most hazardous heavy metals, chromium is often detected in industrial wastewaters originating from many industries such as electroplating, dying, metal polishing, chromic salts industry, textile and leather tanning [1]. In aquatic environment, chromium primarily exists in two stable oxidation states, Cr (III) and Cr (VI) [4].…”

“…Cr(VI) is highly toxic and suspected as carcinogenic agent because it can modifies the process of DNA transcription causing chromosomal aberrations 3 . Furthermore, it can cause epidermal irritation and kidney and gastric damage 4 . Many processes have been used for the removal of Cr(VI) from industrial effluents namely membrane filtration, chemical precipitation, adsorption and ion exchange.…”

Natural zeolite collected from Ende-Flores Indonesia was characterized and activated with acid solution for Cr(VI) adsorption from aqueous solution. This natural zeolite is mainly composed of quartz and 50% mordenite. The kinetic adsorption modeling was fitted best with the pseudo-second-order model, whereas isotherm adsorption followed the Langmuir model with the maximum adsorption (Qmax) of NZ and ANZ are 0.189 mg/g and 1.040 mg/g. Moreover the ANZ was favorable for adsorption of Cr(VI) respectively.
