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.

However, the application is often limited by sensitivity. 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.
