Descrição geral

Polyphosphoric acid (PPA) is an inorganic acid. Galangin-KMnO4-PPA system has been employed for the determination of tryptophan.[1] It participates in the Skraup reaction.[2] It is widely employed reagent for the alkylation and acylation reactions of aromatic and alkenic compounds.[3]

A novel galangin-potassium permanganate (KMnO4)-polyphosphoric acid (PPA) system was found to have an outstanding response to tryptophan (Trp). Trp determination using this KMnO4 -PPA system was enhanced significantly in the presence of galangin. A highly sensitive flow-injection chemiluminescence (CL) method

Based on the chemiluminescence (CL) emission generated from the oxidation of ceftriaxone sodium alkali hydrolysate by potassium permanganate in polyphosphoric acid (PPA), a novel determination method for ceftriaxone sodium was developed by using a flow-injection technique. The calibration curve appears
