In this work, the separation of nine phenolic acids (benzoic, caffeic, chlorogenic, p-coumaric, ferulic, gallic, protocatechuic, syringic, and vanillic acid) was approached by a 3 2 factorial design in electrolytes consisting of sodium tetraborate buffer (STB) in the concentration range of 10–50 mmo...
