Preconcentration of ultra-trace Cu(ii) and Cd(ii) using SPE based on an alizarin complexone modified silica gel with detection using FAAS and determination of ultra-trace Cu(ii) by the naked eye

Abstract

By the gradient elution of Cu(II) and Cd(II), enriched Cu(II) could be completely separated from Cd(II) and monitored with the naked eye using color agent 5-Br-PADAP.

Electrochemical Oxidation of Alizarin Red-S on Glassy Carbon Electrode: Mechanistic Study, Surface Adsorption and Preferential Surface Orientation

“…Dihydroxyanthraquinone (DHAQs) dyes which bearing O-H and C=O moieties and composed a well-known family of dye compounds. Alizarin derivatives constitute an interesting family of anthraquinone dyes and used for determination of metal ions [1][2][3][4] and molecules [5][6][7][8] determination and in textile industry. 9,10 Among them, alizarin red-S dye is extensively employed in textile industry due to their wide range of color shades (yellow to purple) and ease of application.…”

Simultaneous IСP-MS determination of trace metals in natural water and snow after their preconcentration on novel adsorbent based on Al2O3impregnated with Alizarin Complexone

“…In FT-IR spectrum of Al 2 O 3 -PB-AC new peaks are observed at 1420 cm −1 and 1350 cm −1 (bending vibrations of -C-N-H-), 1620 cm −1 (stretching vibrations of -N-C = C-O-), 2850 cm −1 and 2910 cm −1 that can be attributed to the saturated -C-H groups [41,42]. Appearance of these frequency bands in FT-IR spectrum of Al 2 O 3 -PB-AC provides fixation of AC on the surface of Al 2 O 3 -PB.…”

Colorimetric chemosensor for Ni2+ based on alizarin complexone and a cationic polyelectrolyte in aqueous solution

“…Commercially available 3‐[ N , N ‐bis(carboxymethyl)‐aminomethyl]‐1,2‐dihydroxyanthraquinone [alizarin complexone (ALC)] has one amino, two carboxylate, two carbonyl, and two hydroxyl groups that can form a chelate complex with metal ions (Scheme ). It has been demonstrated that ALC is a useful water‐soluble chromogenic chelating reagent for the spectrophotometric determination of metals such as Al 3+ , Ce 3+ , Cu 2+ , and Gd 3+ In addition, the ALC and La 3+ complex has been utilized as a photometric reagent for fluoride ion …”
