An experimental design to optimize the flow extraction parameters for the selective removal of Fe(III) and Al(III) in aqueous samples using salicylic acid grafted on Amberlite XAD-4 and final determination by GF-AAS

Flow injection preconcentration system using a new functionalized resin for determination of cadmium and nickel in tobacco samples

“…A better strategy is to introduce the ligand on the copolymer through a chemical reaction. The functionalization can be made by coupling it to a methylene, azo or other spacer on the matrix [13][14][15]. This procedure produces a much more stable sorbent, although the resulting metal retention capacities are generally at medium levels [16].…”

Functionalization of Silica Nanoparticles by 5-Chloro-8-quinolinol as a New Nanocomposite for the Efficient Removal and Preconcentration of Al3+ Ions from Water Samples

“…As clarified in Table , the adsorption capacity of the silica/5-chloro-8-quinolinol nanocomposite was compared to that of more adsorbents, for example, brilliant green-Amberlite XAD-2, poly­(2-hydroxyethyl methacrylate), tiron-modified resin, XAD-4 functionalized by salicylic acid, activated charcoal, and starch. − Owing to its high adsorption capacity, the silica/5-chloro-8-quinolinol composite outperformed the aforementioned adsorbents.…”

Extraction of heavy metal ions from leachate of cement-based stabilized waste using purpurin functionalized resin

“…Several works on Amberlite XAD series, used as chelating solid support for metal ion extraction, have been reported in the recent years. The examples of the chelating agents employed are pyrocatechol [18], nitroso R salt [10], 2-(methylthio)aniline [19] and pyrocatechol violet [20], o-aminobenzoic acid [21], salicylic acid [22] and dithiocarbamates [23], 1,3-dimethyl-3-aminopropan-1-ol [24], (bis-2,3,4-trihydroxybenzyl)ethylene diamine [17] and phthalic acid [25].…”
