Chitosan functionalized with di-2-propanolamine: Its application as solid phase extractant for the determination of germanium in water samples by ICP-MS
Abstract Cross-linked chitosan was chemically modified with di-2-propanolamine via an arm of chloromethyloxirane (CCTS-DPA resin). The adsorption behavior of the resin towards 62 elements wasExpand
Synthesis of chitosan resin possessing 3,4-diamino benzoic acid moiety for the collection/concentration of arsenic and selenium in water samples and their measurement by inductively coupled
Abstract A chitosan resin functionalized with 3,4-diamino benzoic acid (CCTS-DBA resin) was newly synthesized by using a cross-linked chitosan (CCTS) as base material. The adsorption behavior ofExpand
On-line preconcentration using dual mini-columns for the speciation of chromium(III) and chromium(VI) and its application to water samples as studied by inductively coupled plasma-atomic emission
TLDR
The developed method was successfully applied to the speciation of chromium in river, tap water and wastewater samples with satisfied results. Expand
Synthesis of cross-linked chitosan possessing N-methyl-d-glucamine moiety (CCTS-NMDG) for adsorption/concentration of boron in water samples and its accurate measurement by ICP-MS and ICP-AES.
TLDR
The CCTS-NMDG resin shows high ability in boron sorption with the capacity of 0.61mmolml(-1) and the sorption kinetics of this resin was faster than that of the commercially available resins. Expand
Functionalization of chitosan with 3,4-dihydroxybenzoic acid for the adsorption/collection of uranium in water samples and its determination by inductively coupled plasma-mass spectrometry.
TLDR
The CCTS-DHBA resin was applied to the adsorption/collection of uranium in tap water, river water and seawater samples with satisfactory results, and the validation of the proposed method showed good agreement with the certified values. Expand
Sequential-injection on-line preconcentration using chitosan resin functionalized with 2-amino-5-hydroxy benzoic acid for the determination of trace elements in environmental water samples by
TLDR
The proposed system provides excellent on-line collection efficiency, as well as high concentration factors of analytes in water samples, which results in highly sensitive detection of ultra-trace and trace analysis. Expand
Speciation of chromium in seawater by ICP-AES with dual mini-columns containing chelating resin.
TLDR
A method for the preconcentration and speciation of chromium in seawater was developed by using inductively coupled plasma atomic emission spectrometry (ICP-AES) with dual mini-columns containing a chelating resin. Expand
Synthesis of novel chitosan resin derivatized with serine diacetic acid moiety and its application to on-line collection/concentration of trace elements and their determination using inductively
TLDR
The proposed method with CCTS-SDA resin was successfully applied to the determination of trace elements in river water samples and the limits of detection (LOD) for 13 elements were found to be in sub-ppb level. Expand
Synthesis of chitosan-based resins modified with tris(2-aminoethyl)amine moiety and its application to collection/concentration and determination of trace mercury by inductively coupled plasma atomic
TLDR
The synthesized chitosan-based chelating resin modified with tris(2-aminoethyl)amine moiety showed good adsorption toward mercury in a wide pH range, and the adsorbed mercury can be easily eluted by using 2M HNO(3) without any addition of complexing agent. Expand
Automated Online Preconcentration System for the Determination of Trace Amounts of Lead Using Pb‐Selective Resin and Inductively Coupled Plasma–Atomic Emission Spectrometry
Abstract An automated sequential‐injection online preconcentration system was developed for the determination of lead by inductively coupled plasma–atomic emission spectrometry (ICP‐AES). TheExpand
