“…Nevertheless, for analytical purpose, the advent of atomic absorption spectroscopy (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) turned out to be an improvement for aluminium determination, compared to the traditional fluorometric method. Fluorescence of aluminium complexes is now rather used in highly selective and sensitive methods such as high-performance liquid chromatography with post-column fluorescence detection [13], sequential injection method with fluorescence sensing [14], visual fluorometry on thin layers [15], etc.…”

“…The 1:1 aluminium(III) chelate is fluorescent, whereas the 2:1 chelate is not fluorescent. 31 It was found in earlier studies 29−32 that the pH can control the composition of DHAB and Al 3+ . In order to obtain the fluorescent 1:1 DHAB-Al 3+ complex, the interaction between DHAB and Al 3+ was examined, through UV-Vis and fluorescence spectroscopy, in EtOH-(0.1 M piperazine-N,N-bis(2-ethanesulfonic acid) (PIPES)-KOH) buffer (1:1, v/v) at pH 6.5.…”

Abstract:A ready-to-use multifunctional coordinative system, 2,2'-dihydroxyazobenzene -aluminum (III) (DHABAl 3+ ) , was created to recognize several anions effectively through three channels, namely colorimetric detection, UV-Vis spectroscopy, and fluorescence spectroscopy. Under naked eye visualization, the H 2 PO − 4 can be readily distinguished from the other anions by the DHAB-Al 3+ system through a change in color from reddish-orange to light yellow.was qualitatively detected by using UV-Vis and fluorescence spectra.

“…Most separations have so far focused on the complexes of porphyrins with metal ions using high performance liquid chromatography and high performance thin layer chromatography; [13][14][15][16][17] only a few papers have been presented involving the quantitative analysis of metals using chelating agents by HPTLC. [18][19][20][21] The purpose of this study was to develop a fast, selective, cheap, and simple possible method of separation and simultaneous determination of mercury, zinc, copper, and cobalt in aqueous solutions by HPTLC with the basis of solid phase extraction using TBHPP, TPPP or CMPP ( Figure 1) as complexing agents. By this proposed method, the analysis of metal ions in water and food samples has also been successful.…”

& A method was developed for separation and quantitative determination of mercury, copper, cobalt, and zinc as porphyrin complexes using newly synthesized tetra-(3-bromo-4-hydroxyphenyl) porphyrin (TBHPP), tetra-(4-phenoxyphenyl) porphyrin (TPPP) and tetra-p-chloromethylphenyl porphyrin (CMPP) in aqueous medium by HPTLC densitometry. The method involves enrichment of metal ions as metal complexes with octadecyl cartridges and elution using tetrahydrofuran. The analysis was performed on HPTLC silica gel plates with acetone-chloroform (2:8, v=v) as the mobile phase for TBHPP and TPPP quantification and dichloromethane-chloroform-hexane (1:1:3, v=v) for CMPP quantification. Quality parameters were confirmed and detection limits were ranged from 0.16 to 0.92 ng lL À1 . Detection was performed densitometrically in absorption-reflection mode around 420 nm. The method was found to be simple, precise and accurate for the determination of these metal ions in water and food sample.
