Determinação da Con centração de Fosfato em Amostras de Detergentes em Pó Utilizando Detecção Titulométrica

Abstract: O uso excessivo de fósforo na forma de tripolifosfato de sódio (STPP) em detergentes em pó tem e contribuído de maneira significativa no processo de eutrofização da águas e consequentemente na poluição dos corpos hídricos. Visando a redução e eventual eliminação do uso de fosfato nos detergentes, o Conselho Nacional do Meio Ambiente criou a resolução CONAMA 359/05, que dispõe sobre a regulamentação do teor de fósforo em detergentes em pó para o uso no mercado nacional. O presente trabalho tem como objetivo det… Show more

“…According to Nur et al (2016), the phosphate, another parameter seen in this study, in addition to agricultural products, mainly fertilizers and fertilizers, contains a high concentration of phosphorus, which is one of the three main components for the growth of plants, and one of the components used in the composition of household and industrial detergents. In the case of detergents, the inorganic phosphates have the function of neutralizing certain metal ions found in water, such as the calcium and magnesium, reducing the water hardness, and, thus, maintaining the alkaline medium, preventing the dirt from re-fixing in the tissues (SOUZA et al, 2010).…”
