WebbPQ detection has been achieved using various methods such as high-performance liquid chromatography [6,7],gas chromatography-mass spectrometry [8],spectrophotometry [9],fluorescence [10],and capillary electrophoresis [11].Although paraquat can be rapidly and selectively detected using these methods,disadvantages such as low recognition … Potassium ferricyanide is the chemical compound with the formula K3[Fe(CN)6]. This bright red salt contains the octahedrally coordinated [Fe(CN)6] ion. It is soluble in water and its solution shows some green-yellow fluorescence. It was discovered in 1822 by Leopold Gmelin. Visa mer Potassium ferricyanide is manufactured by passing chlorine through a solution of potassium ferrocyanide. Potassium ferricyanide separates from the solution: 2 K4[Fe(CN)6] + Cl2 → 2 K3[Fe(CN)6] + 2 KCl Visa mer Like other metal cyanides, solid potassium ferricyanide has a complicated polymeric structure. The polymer consists of octahedral [Fe(CN)6] centers crosslinked with K ions that are bound to the CN ligands. The K ---NCFe linkages break when the solid is … Visa mer Potassium ferricyanide has low toxicity, its main hazard being that it is a mild irritant to the eyes and skin. However, under very strongly acidic … Visa mer • Ferricyanide • Ferrocyanide • Potassium ferrocyanide Visa mer The compound is also used to harden iron and steel, in electroplating, dyeing wool, as a laboratory reagent, and as a mild oxidizing agent in organic chemistry. Photography Visa mer Prussian blue, the deep blue pigment in blue printing, is generated by the reaction of K3[Fe(CN)6] with ferrous (Fe ) ions as well as K4[Fe(CN)6] with ferric salts.
