Solid phase extraction of copper(II) ions using C18-silica disks

Solid phase extraction of ultra trace copper(II) using octadecyl silica membrane disks modified by a naphthol-derivative Schiff's base. Anal. Chim. Acta (2000) There are more references available in the full text version of this article. Cited by (30)The solid-phase extraction step can be conducted in the field and then the disks can be mailed to a laboratory for the analysis, eliminating the cost of transporting large volumes of water samples. Furthermore, the color of the used extraction disk provides an initial estimate of the degree of contamination for some transition metals (for example, Ni Determination of Trace Metals in Drinking Water Using Solid-Phase

Micro-solid-phase extraction ScienceDirect

16 Micro-solid-phase extraction. Microscale sorbent–based sample preparation techniques comprise of nonmembrane and membrane-protected microextraction, both of which are miniaturized alternatives to solid-phase extraction (SPE). Pipette-tip SPE, microextraction in a packed sorbent, and disposable pipette The most commonly used methods for the separation and preconcentration of trace copper are liquid-liquid extraction (LLE) [17,18], solid-phase extraction [19,20], and cloud point extraction [21,22]. These techniques have their own advantages, but they suffer from one or more of the following drawbacks: long analysis Determination of Ultra-Trace Amounts of Copper in
