CHEMICAL ANALYSIS OF A TYPICAL PHOSPHORUS SMOKE AND FLARE COMPOSITION,
Abstract
A scheme for the chemical analysis of a typical phosphorus composition of ZnO, Mg, Mn02, phosphorus, and linseed oil is described in detail. ZnO is removed by chromic acid solution, Mg by acetic acid, and the resulting mixture of phosphorus, MnO2, and linseed oil is brought into solution with HN3 and H2O2. Silica is removed and weighed. Mn is precipitated out as MnO2 and ignited to Mn3O4, EDTA is employed to chelate ions that might interfere with the phosphorus determination, and the phosphate precipitated out as the phosphomolybdate. Linseed oil is estimated by difference. (Author)
