DETERMINATION OF IRON MANGANESE, ETC. 8$ 6. Method of llous-nnGhXiiJT for deicnn<strong>in</strong>ation of Phos- phorus. See Annak's de Chimie et de Physique, June, 1 8; 5, and abstract <strong>in</strong> American Chemist, Vol. VI, p. 275. 7, l^or additional methods consult also papers by Alfred H Allen, Chem. Neivs, XXIX, p. 91. and paper by Hamilton, Qmn, Nnus, Vol. XXI. p. 147- Compare Crookes' Sdect Methods, pp. 84-89. D—Determ<strong>in</strong>ation of Iron Manganese, etc- <strong>The</strong> iron may be determ<strong>in</strong>ed by difterence or by Margue- rite's method, <strong>in</strong> which case dissolve 0.2 grms. of pig-iron <strong>in</strong> H.SO^, and proceed as usual. It is advisable to use a rather dilute solution of K.Mn.O^ towards the close of the oxidation. For the determ<strong>in</strong>ation of the bases of Groups II, iU, and IV, dissolve 10 or 20 grms of pig-iron <strong>in</strong> HCl, remove the SiO, by dry<strong>in</strong>g thoroughly, and proceed as <strong>in</strong> Analysts No. 21. r,^ [ <strong>The</strong> manganese may be thrown down <strong>in</strong> the filtrate, trom the basic acetate of iron by means of brom<strong>in</strong>e, or <strong>in</strong> the absence of calcium, magnesium, etc., by hydrodisodic phosphate. See Fres., § 109, 3, also § 3i8, 6. For other methods of estimat<strong>in</strong>g manganese see articles by Samuel Peters m Chem. News, Vol. XXXIII, p, 35, and by William Gah braith, <strong>in</strong> Chem. News, Vol, XXXIII, p, 47- See also paper by Charles H. Piesse <strong>in</strong> Chefu. News, Vol.XXIX., pp. 57and no. For testimony as to the condition <strong>in</strong> which silicon exists <strong>in</strong> pig-iron, see paper by E. H, Morton, Cheni. News, Vol. XXIX., p. 107.
