Tartrazine Dye and Bovine Serum Albumin: the Influence of pH on Adsorption Process
Multilayers from Tartrazine dye (Tart) alternated with bovine serum albumin (BSA) were successfully prepared and a uniform growth has been observed. The influence of two values of Tart solution pH (3 and 7.5) on adsorption process of this molecule on BSA monolayer at physiological pH was investigated using kinetics and isotherms of adsorption, as well as thermostimulated adsorption experiments. All effects found by the changing of the pH were explicated mainly taking into account the ionic attraction (Tart at pH 3) and ionic repulsion (Tart at pH 7.5) that occurs during the adsorption process of Tart onto BSA monolayer.
