Fabrication, Characterization, Ion-Exchange studies and binary separation of Polyaniline/Ti(IV) iodotungstate composite Ion-Exchanger for the treatment of water pollutants

Titanium-embedded nanocomposite material stimulates ion-exchange characteristics to deal with pollutants in aquatic environment

“…Above 530°C, a sharp weight loss up to 720°C (5%) is observed, which indicates the complete conversion of the nanocomposite material into metal oxide (70%) as nal product. Finally, the concurrent curve of TGA-DTG studies inferred that PANI/TIM nanocomposite ion-exchanger was slightly less stable than TIM but more stable than organic counterpart PANI [5].…”

“…From these values, the calculated average particle size of PANI/TIM is found to be in the range of ~ 27 nm. Hence, XRD studies clearly depict that the formation of PANI/TIM nanocomposite ion-exchanger leads to decrease in size compared to the conducting polymer PANI [5] and inorganic counterpart.…”

“…The peaks at 617 cm − 1 and 650 cm − 1 are attributed to C-H out-of-plane bending vibration. Other characteristic bands associated with the individual parts of the inorganic precipitate TIM and PANI [5] were re ected with a noticeable shift in the PANI/TIM nanocomposite ion-exchange material. It gives evidence for the encapsulation TIM in the polymeric matrix of polyaniline and forms PANI-TIM nanocomposite material.…”

“…It have been broadly utilized as a part of the different elds such as sensors, batteries, catalysis, supercapacitors, electronic devices and anticorrosion coatings due to its relatively low cost, easily synthesized, high conductivity, non-toxic, excellent chemical and environmental stability [1][2][3][4]. In the present study, we utilized the conducting polymer PANI which is synthesized and reported earlier [5].…”

Adsorption and Reduction of Aqueous Cr by FeS-Modified Fe-Al Layered Double Hydroxide

“…In recent years, numerous treatment techniques have been developed to deal with Cr pollution from the aquatic ecosystems, such as adsorption [12], ion exchange treatment [13], chemical precipitation [14][15][16], bio-removal [17], and membrane filtration [18]. Among these, chemical fixation technology has attracted more attention due to its convenient operation, high efficiency, low secondary pollution, and relatively low cost [14][15][16].…”
