“…LC offers at least one potential advantage to ICP-MS users as well: the ability to remove a troublesome matrix on-line. Papers describing the off-line preconcentration of trace metals in seawater (32) and removal of matrix elements by ion exchange (33) using ICP-MS detection have been published.…”

“…Several kinds of chelating resins have been proposed for the determination of transition metals or rare-earth elements in seawater samples. [13][14][15][16][17][18] Since ICP-MS enables multi-element detection simultaneously, it is desirable to determine as many trace elements as possible, including transition metals and rareearth elements, for a comprehensive study of the distribution of trace elements in a marine environment.…”

Trace metals in aquatic systems have become a significant topic of concern in various fields associated with water quality, as well as a concern of the general public. Among several kinds of water samples, the determination of trace metals in seawater is the most interesting challenge in analytical chemistry, because of high concentrations of matrix and very low concentrations of analytes.Although inductively coupled plasma-mass spectrometry (ICP-MS) provides most accurate, sensitive and reliable detection for trace metals, its low tolerance of dissolved solids prohibits the direct analysis of trace metals in seawater samples by using this instrument. In the determination of trace metals in seawater by ICP-MS, the transition metals are interfered by polyatomic ions derived from alkali and alkalineearth metals, such as oxide and hydroxide. 1-3 Therefore, preconcentration and matrix separation are required prior to the determination of trace metals by ICP-MS.Sample pretreatment for the collection/concentration of analytes and the removal of matrix and interfering substances using chelating resin, such as commercially available iminodiacetate chelating resin, known as Chelex-100, 4,5 Muromac A-1 6-9 and Toyopearl AF Chelate 650M, [10][11][12] have been used for the determination of transition metals or rare-earth elements in seawater by ICP. The resins, however, can separate only some parts of alkali and alkaline-earth metals from analytes, and such sample matrix as Na can remain with analytes and interfere with the determination of trace metals. Several kinds of chelating resins have been proposed for the determination of transition metals or rare-earth elements in seawater samples. 13-18Since ICP-MS enables multi-element detection simultaneously, it is desirable to determine as many trace elements as possible, including transition metals and rareearth elements, for a comprehensive study of the distribution of trace elements in a marine environment.Among the chelating reagents, ethylenediamine tetraacetic acid (EDTA) is one of the most stable chelating reagents, and can form chelates with a number of trace metal ions. Therefore, EDTA is a suitable chelating moiety for a multianalyte adsorption. Some chelating resins that possess the EDTA moiety have been synthesized using several kinds of polymer matrixes, such as cellulose, 19 glycidyl methacrylate divinylbenzene, 20 or chitosan. [21][22][23] Nowadays, a chelating resin that possesses the EDTA moiety, Nobias Chelate-PA1, has been commercially available (Hitachi High Technologies, Tokyo, Japan). The resin has a good adsorption ability of transition and rare-earth metals, and can separate them from alkali and alkaline-earth metals. However, a high concentration of nitric acid was necessary to recover analytes from the resin, acetone was necessary for cleaning the resin, and furthermore resin particles were very small, which makes it difficult to use in a batchwise or a column pretreatment method, because of the slow flow rate.We are mainly interested in a sorbent b...

“…Calibration using matrix matched standards is also a practical method of correction if the composition of the sample is known and high purity standards are available. The standard additions method (37)(38)(39) has been used as a traditional way of overcoming the matrix effects with some success in ICP-MS as well as in almost all techniques of spectroscopy.…”
