Determination of Elements in Energy Drinks by ICP OES with Minimal Sample Preparation
Foram comparados vários procedimentos de preparo de amostras, isto é, decomposição total de uma mistura HNO3/H2O2 em placa de aquecimento, decomposição parcial por meio de solubilização em aqua regia e diluição com solução de HNO3 de baixa concentração, para determinação do conteúdo total de Ba, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb, Sr e Zn em bebidas energéticas utilizando espectrometria de e...
متن کاملEvaluation of Metal Ions in Rice Samples: Extraction and Direct Determination by ICP OES
Foi desenvolvido um método de extração de íons de metais presentes em amostras de arroz, usando solução amoniacal de EDTA (ácido etilenodiamino tetraacético), pH ≥ 10, como agente extrator, sob as seguintes condições otimizadas: 0,20 g de amostra de arroz e 5,00 mL da solução amoniacal de EDTA, com 5 min de tempo de exposição em ultrassom. Usando condições robustas de ICP OES (espectrometria de...
متن کاملSimultaneous separation and determination of Tl(I) and Tl(III) by IC-ICP-OES and IC-ICP-MS
A new hyphenated method was developed for the speciation of Tl. In this method, Tl(III) was complexed with DTPA to form a Tl(III)-DTPA anionic complex. Tl(I) did not form a complex with DTPA. The two species were separated simultaneously by means of ion chromatography using a Dionex cation exchange guard column, CG12A, and 15 mmol/l nitric acid as eluant. When ICP-OES was used as detector the d...
متن کاملsynthesis and determination of lead (ii) sulfide nanoparticles in rat organs by icp-oes
recent studies have reported that metal sulfide nanoparticles had potential adverse effects. in this research, lead (ii) sulfide nanoparticles have been synthesized under different reaction conditions. scanning electron microscopy and x-ray diffraction were used to characterize the particle size and morphology. distribution, accumulation and toxic effects of nanoparticles on rats as a biologic...
متن کاملComparison method for uranium determination in ore sample by inductively coupled plasma optical emission spectrometry (ICP-OES).
A comparison method for the determination (without sample pre-concentration) of uranium in ore by inductively coupled plasma optical emission spectrometry (ICP-OES) has been performed. The experiments were conducted using three procedures: matrix matching, plasma optimization, and internal standardization for three emission lines of uranium. Three wavelengths of Sm were tested as internal stand...
