“…Among them, adsorption has been recognized as one of the most promising methods due to its simplicity, high efficiency, and wide-range availability [2,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

“…As is well known, many kinds of pollutants can be encapsulated into the cavities of b-CD, therefore it can be used as a substitute for activated carbon materials to remove coloured impurities, especially the dyestuff from aqueous solution. Furthermore, the EDTA-crosslinked b-CD (EDTA-b-CD) biopolymer was fabricated to remove lanthanum(III), cerium(III) and europium(III) from aqueous solution [31]. So far, several studies have been carried out on b-CD, modifying its basic structure to significantly improve its adsorption efficiency.…”

In this paper, highly absorbent poly(vinyl alcohol-co-ethylene) nanofibre membranes modified by b-cyclodextrin were prepared to adsorb dyestuff from water, and 1,2,3,4-butanetetra carboxylic acid was used as a crosslinking agent, which greatly enhanced the adsorption capacity of the modified membranes. Field emission scanning electron microscopy and Fourier Transform-infrared spectroscopy were used to characterise the surface morphology and chemical structures of the membranes. Methylene Blue (MB) was used as the main adsorbed dye. The effect of pH value and concentration of the MB solution were also investigated, and equilibrium adsorption reached 139.2 mg/g when the pH value was 10.0. The adsorption process fitted well with the Langmuir adsorption isotherm model and was in accord with the pseudo-secondorder kinetic model. Moreover, the modified membranes proved to have selective adsorption, especially for some cationic dyes other than MB, and had the potential to be recycled multiple times.

“…For example, trace elements have been determined from seawater by ICP-MS after pre-concentration using a column filled with iminodiacetic acid resin [18] and analysis of trace metals in seawater conducted using nitrilotriacetate resin [19]. Furthermore, in a very recent paper Cyclodrexin modified with EDTA was successfully used for the preconcentration of rare earth elements prior to analysis with ICP-OES [20].…”

This study focuses on the adsorption and preconcentration of various metals by silica gel surfaces modified with aminopolycarboxylic acids namely ethylenediaminetetraacetic acid or diethylenetriamine-pentaacetic acid. The adsorption performance of the studied materials was determined in mixed metal solutions and the adsorption isotherm studies were conducted for cobalt, nickel, cadmium, and lead. The results were modeled using various theoretical isotherm equations, which suggested that two different adsorption sites were involved in metal removal although lead showed clearly different adsorption behavior attributed to its lowest hydration tendency. Efficient regeneration of the adsorbents and preconcentration of metals was conducted with nitric acid. Results indicated that the metals under study could be analyzed rather accurately after preconcentration from both pure, saline and ground water samples.
