In a flame test, potassium and its compounds emit a lilac color, which may be masked by the strong yellow emission of sodium if it is also present. Cobalt glass can be used to filter out the yellow sodium color.[9] Potassium concentration in solution is commonly determined by flame photome...
In the case of nitrate, the majority of applications for its determination are based on copperized-cadmium or cadmium-coated zinc reductor columns, which are generally used for reducing nitrate to nitrite. After formation of color, specific reagents are added and nitrate is determined from the dif...
FlameEnergetic materialsGreen chemistryRed pyrotechnic flames are mostly produced using strontium compounds. Flame color quality is dependent on the chemical composition of the mixture. The emission spectrum produced by strontium monohydroxide (SrOH) and strontium monochloride (SrCl) species in red colored...
protocol. The development of yellow color confirmed the presence of phosphorus. The absorbance was taken at 420 nm on a UV-Spectrophotometer for the final determination of phosphorus in the sample [46]. In the analysis of potassium, the digested solution was run directly on a flame photometer ...

Frozen sections 10-25 micrometers thick, 5% aqueous solution of potassium ferricyanide for 2 h (37 degrees C), 10% aqueous solution of silver nitrate for about one h (37 degrees C) or until sections obtain a light brown tint, ammoniacal silver solution, reduction in 20% formalin, gold ...
Plant samples were digested using HNO3-HClO4 (3:2) to determine K by diluting and P by the Vanadomolybdate yellow color method through a flame photometer and spectrophotometer, respectively [32]. N was determined by the micro-Kjeldahl method [32]. The different agronomic parameters [33,34]...
