Última Multivariate optimization of a method for antimony determination by hydride generation atomic fluorescence spectrometry in hair samples of patients undergoing chemotherapy against Leishmaniasis Anais da ABC (AABC) CARDOZO,MANUELLE C.; CAVALCANTE,DANNUZA D.; SILVA,DANIEL L.F.; SANTOS,WALTER N.L. DOS; BEZERRA,MARCOS A.. ABSTRACT A method was developed for determination of total antimony in hair samples from patients undergoing chemotherapy against Leishmaniasis based on the administration of pentavalent antimonial drugs. The method is based on microwave assisted digestion of the samples in a pressurized system, reduction of Sb5+ to Sb3+ with KI solution (10% w/v) in ascorbic acid (2%, w/v) and its subsequent determination by hydride generation atomic fluorescence spectrometry (HG-AFS). The proportions of each component (HCl, HNO3 and water) used in the digestion were studied applying a constrained mixtures design. The optimal proportions found were 50% water, 25% HNO3 and 25% HCl. Variables involved in the generation of antimony hydride were optimized using a Doehlert...

DOS; SAUTHIER,MARIA CELESTE S.; CAVALCANTE,DANNUZA D.; BENEVIDES,CLÍCIA M.J.; DIAS,FÁBIO S.; SANTOS,DANIELE C.M.B.. ABSTRACT The atemoya is a hybrid fruit obtained by crossing of cherimoya (Annona cherimola Mill.) with sweet sop (Annona squamosa L.). The information about chemical composition of atemoya is scarce. The mineral composition was evaluated employing Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) and the centesimal composition and the physico-chemical parameters were assessed employing procedures described in the AOAC methods. The total phenolic compounds (TPC) and total flavonoids (TF) were determined using spectroanalytical methods. Considering the Reference Daily Intake (RDI), the concentrations of K, Cu and Vitamin C found in atemoya were the highest, representing about 32, 23 and 37% of the RDI, respectively. The total carbohydrates... Tipo: Info:eu-repo/semantics/article Palavras-chave: Atemoya; Food composition; ICP OES; Flavonoids; Phenolics.
