Comparative Study on Metal Extraction Properties of Empore SDB‐XC and Amberlite XAD‐4 Grafted by Salicylic Acid and its Derivatives via Different Bridges

Preconcentration and determination of trace metal ions from aqueous samples by newly developed gallic acid modified Amberlite XAD-16 chelating resin

“…In continuance to the research going on in our laboratory [4][5][6][7], an approach for the removal of trace metal ions using newly synthesized gallic acid (GA) coupled with Amberlite XAD-16 via diazo group [29,34] was adopted and its application for the preconcentration of metal ions in natural water samples was studied. The optimal analytical conditions including pH, rate of sorption, flow rates of sample, preconcentration factor, sorption capacity and matrix effects were also investigated.…”

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

“…Pyrolytically coated graphite furnace tubes were used. Table 1 Physico-chemical characteristics of the modified resin [23] Mean specific area 800 m 2 g −1 BET method Mean porous volume 0.9 ml g −1 Mercury intrusion porosimetry Mean porous diameter 4 nm Mean bead diameter 350 nm by sieving Adsorption capacity (batch method)…”

“…One way to selectively uptake metals of interest is obviously the use of chelating sorbents, and especially sorbents onto which specific ligands have been grafted or immobilized [20][21][22][23]. Using of such chelating sorbents may be interesting in analytical field too, as a separation support in solid-phase extraction (SPE) or in solid-phase microextraction (SPME).…”
