Facile synthesis of triazole and carboxyl-functionalized cellulose-based adsorbent via click chemistry strategy for efficient Gd(III) removal

Rational fabrication of a new ionic imprinted carboxymethyl chitosan-based sponge for efficient selective adsorption of Gd(iii)

“…To investigate the effect of solution pH on the adsorption capacity of adsorbents, the pH tests were conducted in the pH range of 2-7 due to the fact that Gd(III) could form the precipitate under alkaline conditions. 20 As observed from Fig. 7, the Gd(III) adsorption capacities for all of the adsorbents continually increase as the increasing pH and reach the maximum at pH ¼ 7.…”

“…However, Gd( iii ) commonly co-exists with other REMs ions in practical aquatic environment, such as NdFeB permanent magnet/magnetic refrigeration wastewater. 20 Moreover, the similarity in physicochemical properties among REMs ions hinders the obtainment of high-purity Gd( iii ). As a result, designing a high-efficiency adsorbent that can realize the selective removal of Gd( iii ) from water is extremely necessary.…”

Hyperbranched polymer immobilized palladium nanoparticles as an efficient and reusable catalyst for cyanation of aryl halides and reduction of nitroarenes

“…XPS spectra in N 1s region showed three peaks centered at 398.6, 400.0 and 401.6 which are related to N=N, N-C and quaternary nitrogen, respectively (Fig. 3a) [64,65]. Appearance of Br 3d5/2 and Br 3d3/2 doublet at 67.2 and 68.2 confirmed presence of Br in the structure (Fig.…”

Selective adsorption of gadolinium from real leachate using a natural bentonite clay

“…Adsorption capacity and selectivity are important factors in assessing the practicability of any adsorbent. Therefore, a comparison of Gd 3+ adsorption between Bentonite clay used in this work and other adsorbents reported in the literature was assessed [41][42][43][44][45][46][47][48] (see Table 3). The maximum adsorption capacity of our bentonite clay at pH 6 was found to be 121.5 mg g − 1 , which is the third highest among those of other materials presented in Table 3.…”
