Polyaniline based materials as a method to eliminate haloanisoles in spirits beverages
Valdés, Oscar; Marican, Adolfo; Avila-Salas, Fabian; Castro, R. I.; Amalraj, John; Laurie, Felipe; Santos, Leonardo S. (2018)In this research, the abilities of two polyaniline-based materials (PANI-EB and PANI-ES) were evaluated as potential fining agents to eliminate 2,4,6-trichloroanisole (TCA) and 2,4,6-tribromoanisole (TBA). The results ...
