چکیده

A seawater sample was analyzed for its lanthanoids (Ln’s) contents by inductively coupled plasma mass spectrometry (ICP-MS). The analytical procedure included the pre-concentration and partial purification of Ln’s with a chelating resin disk and the employment of the combination of the internal standard and standard addition methods in ICP-MS, which seemed indispensable for the determination of low-level Ln’s by ICP-MS. The recoveries of the Ln’s with the disk were mostly 70% or better with the concentration factor of 200. The measured concentrations of Ln’s were on the order of ng·dm or lower and reasonable except that of neodymium and samarium.

Sample pretreatment using chitosan-based chelating resin for the determination of trace metals in seawater samples by inductively coupled plasma-mass spectrometry.

A sample-pretreatment method using a chitosan-based chelating resin, ethylenediamine-N,N,N'-triacetate-type chitosan (EDTriA-type chitosan), was developed for the preconcentration of trace metals in seawater and separation of the seawater matrix prior to their determination by inductively coupled plasma-mass spectrometry (ICP-MS). The resin showed very good adsorption for transition metals and ...

Trace elements determination in seawater by ICP-MS with on-line pre-concentration on a Chelex-100 column using a ‘standard’ instrument setup.

Trace element determination in seawater is analytically challenging due to the typically very low concentrations of the trace elements and the potential interference of the salt matrix. A common way to address the challenge is to pre-concentrate the trace elements on a chelating resin, then rinse the matrix elements from the resin and subsequently elute and detect the trace elements using induc...

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.

A chitosan resin derivatized with 3,4-dihydroxybenzoic acid moiety (CCTS-DHBA resin) was newly synthesized for the collection/concentration of trace uranium by using cross-linked chitosan (CCTS) as base material, and the adsorption behavior of uranium as well as 60 elements on the resin was examined by passing the sample solutions through a mini-column packed with the resin. After the elution o...

Speciation of chromium in seawater by ICP-AES with dual mini-columns containing chelating resin.

A method for the preconcentration and speciation of chromium in seawater was developed. On-line preconcentration and determination were carried out by using inductively coupled plasma atomic emission spectrometry (ICP-AES) with dual mini-columns containing a chelating resin. In this system, Cr(III) was collected on the first column. The effluent containing residual chromium from the first colum...
