“…It should be noted that the development of optical oxalate detectors is of great interest in the analysis of food, natural waters and urine due to its detrimental effects on the human body and its importance in the diagnosis of a number of diseases. [21] Experimental Section General: All solvents and chemicals were commercially purchased reagent-grade quality and used as supplied without further purification, except 1,3,5-tris(aminomethyl)-2,4,6-triethylbenzene and tbN 4 , which were prepared according to literature methods. [22,23] NMR spectra used for characterisation of products and binding experiments were recorded using a Bruker Avance 400 instrument.…”

“…This reagent was also used for the determination of glutathione and cysteine, using Ce(IV) as an oxidant (20,22). One of the early reports on the use of Ru(phen) 3 2+ was on the analysis of oxalic acid in food samples using HPLC (23,24).…”

“…A maioria dos procedimentos de análise de oxalato são, muitas vezes, complicados e/ou dispendiosos devido aos reagentes e aparelhos necessários [2,8,9,10,13]. A detecção do oxalato é feita de forma indireta em muitos casos.…”

“…Contínuas investigações vêm sendo feitas enfocando este íon, bem como seus sais insolúveis. A grande demanda está principalmente no campo da medicina, laboratórios de análises clínicas e nas indústrias farmacêutica e de alimentos, tornando muito importante os estudos relacionados com o comportamento de sistemas contendo o íon oxalato e seus sais [6].A maioria dos procedimentos de análise de oxalato são, muitas vezes, complicados e/ou dispendiosos devido aos reagentes e aparelhos necessários [2,8,9,10,13].
