Planejamento experimental na determinação do ponto de turbidez dos tensoativos Ultranex/ Experimental planning in determining the turbidity point of Ultranex surfaces

Abstract

Alguns trabalhos encontrados na literatura comprovam a viabilidade do uso do ponto de turbidez de tensoativos não iônicos em eficientes métodos de extração para a separação, pré-concentração ou purificação de uma variedade de substâncias, incluindo íons metálicos e vários compostos orgânicos. A extração desses solutos se dá por uma característica particular dos tensoativos não iônicos, o chamado ponto de turbidez que tem origem nas propriedades que apresentam esses tensoativos. O objetivo deste trabalho é a determinação do ponto de turbidez dos tensoativos da linha ULTRANEX (nonilfenol etoxilados), com diferentes graus de etoxilação. O planejamento experimental possibilitou a determinação de um modelo significativo que prediz o ponto de turbidez do tensoativo em função dos graus de etoxilação e da concentração utilizada.

Keywords

Ponto de turbidez, planejamento experimental e tensoativos ultranex.
