ESPECTROFOTOMETRIA UV VISIBLE PDF

  • No Comments

Espectrofotometria na região UV-VIS do espectro eletromagnético é uma das técnicas analíticas mais empregadas, em função de robustez, custo relativamente. A determinação de S por espectrofotometria UV-Vis é comumente realizada através de uma análise turbidimétrica. Contudo, para que isso seja possível, faz- se.

ABSTRACT Dry ashing, dissolution in aqueous medium or wet digestion methods were evaluated for sample preparation of shampoo for the subsequent indirect determination of sulfur by UV-Vis spectrophotometry.

Spectrophotometry is one of the most widespread analytical techniques due to its simplicity, reliability, and low-cost instrumentation for both direct measurements and coupled to other techniques or processes such as chromatography, electrophoresis and flow analysis.
