“…The change in the SEM images of the microspheres after the grafting, the sulfonation, and the protonation also confirmed the success of the modification process from the CMS to the CGS. After the grafting and chemical modification, the resultant microsphere still kept its spherical morphology, which showed its potential use in column adsorption [29].…”

The separation of Li+ from an aqueous solution has received much attention in recent years because of its wide application in batteries and nuclear energy. A cellulose microsphere adsorbent with sulfonic acid groups (named as CGS) was successfully prepared by the pre-irradiation-induced emulsion graft polymerization of glycidyl methacrylate onto cellulose microspheres through subsequent sulfonation and protonation. The adsorption performance of Li+ onto the CGS adsorbent is investigated in detail. The as-prepared CGS adsorbent exhibited fast adsorption kinetics and a high adsorption capacity of Li+ (16.0 mg/g) in a wide pH range from 4 to 10. The existence of K+ and Na+ was found to have the ability to affect the adsorption capacity of Li+ due to the cation-exchange adsorption mechanism, which was further confirmed by X-ray photoelectron spectroscopy (XPS). The column adsorption experiment indicated that the adsorption capacity of CGS agreed well with the batch adsorption, and a fast desorption could be obtained in 10 min. It is expected that CGS has potential usage in the adsorption separation of Li+ from an aqueous solution.

“…IR spectra of the aerogels and BP-IDA, 4-bpmb ( Figure 6) further confirm the coordination of the carboxylate and pyridine group to metal ions, as evidenced by the shift of the C＝O stretching frequency from ca. 1721 cm 1 for the uncoordinated carboxylic acid to 1619 cm 1 , the C＝N stretching frequency [42] from ca. 1418 cm 1 for the uncoordinated pyridine to 1384 cm 1 for the aerogels.…”

In this work, a novel and simple flexible aromatic multi-carboxylate compound N,N'-(4,4'-biphenylyl) iminodiacetic acid (BP-IDA) was synthesized, with which two new stable metal-IDA gels (denoted as MIG1 and MIG2) with three-dimensional network structures have been prepared successfully by employing Cr 3＋ and Al 3＋ as the metal ions, respectively. The rheological performance was investigated by means of dynamic rheology measurement. The morphology and microstructure were characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction technique. Nitrogen sorption isotherm measurement suggests that the MIG1 aerogel has considerable porosity with the Brunauer-Emmett-Teller specific surface area up to 760 m 2 •g 1 . Owingto easy preparation, good stability, and three-dimensional network structure, the as-prepared metal-organic gels will possess potential applications in separation, catalysis, and drug delivery.

“…[5][6][7][8] Adsorption method is more effective method to recover the low concentration of gold from the view of cost and operation. 9,10 The resin is seen as a more potent adsorbent because of its higher adsorption capacity, easy desorption, and regeneration under mild conditions, high stability and long cycle life. However, the common resins have almost no recognition selectivity performance for AuCl 4 − .…”

In this article, a new surface imprinted polymer D301-g-IIPDMC is successfully prepared using AuCl 4 − as a template. The adsorption and recognition performances of D301-g-IIPDMC for AuCl 4 − are studied by using a static method and competitive adsorption experiment. The experimental results show that D301-g-IIPDMC possesses very strong adsorption affinity and excellent recognition for AuCl 4 − . The adsorption capacity of D301-g-IIPDMC for AuCl 4 − is 831.08 mg/g, and the selectivity coefficient relative to CuCl 4 2− is 128. The adsorption behavior is an endothermic spontaneous process, and fit well with pseudo-second order kinetic model and Freundlich adsorption isotherm model. Besides, D301-g-IIPDMC is desorbed easily and exhibits excellent reusability.
