“…[1][2][3][4] For example, selenium compounds have been reported to have anticarcinogenic activity and to prevent heavy-metal toxic effects. [5][6][7] On the other hand, an excessive intake of selenium can lead to toxic responses, including alkali disease and blind staggers.…”

“…J acid, hexamethyleneiminecarbodithiote, methylene blue, 2,3-diamino-1-4-dibromonaphthalene, 2, 3-diaminonaphthalene, thionin, maxilon blue-SG, iodide-rhodamine, 5,5-dimethyl-1,3-cyclohexanedione, methdilazine hydrochloride, 4-aminoantipyrine+ N-(naphthalen-1-yl)ethane-1,2-diamine dihydrochloride, etc. are reported for the spectrophotometric determination of selenium [13][14][15][16][17][18][19][20][21][22][23][24]. Most of them either suffer with interference of some ions commonly associated with Se in environmental samples, or/and require a prolonged standing time to develop a maximum and constant absorptivity of the species at the elevated temperature.…”

“…5,17 Embora a dissolução do shampoo em meio aquoso permita que os constituintes estejam presentes na solução, interferências relacionadas à matriz da amostra e a possibilidade do analito não estar disponível para ser detectado podem comprometer a exatidão dos resultados. Diante disso, dentre os métodos comumente utilizados para o preparo de amostras de shampoo, pode-se destacar a decomposição por via seca em forno mufla 18 e a decomposição por via úmida com aquecimento convencional 19 ou assistida por radiação micro-ondas. 20,21 No entanto, é importante mencionar que esses métodos de preparo de amostras ainda não foram utilizados para a posterior determinação de S em shampoo.…”
