Engineered polyaramides for extraction of bioamines from water.

ABSTRACT: Biogenic amines (BAs) are prevalent in fermented foods, protein-rich meats, and brewed food additives. High concentrations of BAs can induce health issues such as headaches, high blood pressure, and palpitations. Polyaramides (PAs) prepared from the reaction of trimesoyl chloride with ethylene diamine (ED), p-xylene diamine (PXD), and m-xylene diamine (MXD) and characterized using FTIR, XRD, SEM, TGA, and DLS measurements. All PAs were used for the removal of five biogenic amines (i.e., putrescine, spermidine, spermine, tryptamine, and tryptophan) from water. All PAs showed high removal efficiencies for biogenic amines, and the data collected fit well with the Langmuir isotherm and pseudo-second-order kinetic models. Among three different polymers, PA3 showed exceptional adsorption capacit
