    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1901 Excerpt: ...The uranium, copper and iron are separated as follows: The hydrochloric acid solution--which contains these three metals--is nearly neutralized with ammonia, and ammonium carbonate added in excess, which precipitates the iron as hydroxide. The precipitation should be made in the cold. The greater part of the carbon dioxide in the filtrate from the iron is removed by boiling, after which the copper is precipitated by means of hydrogen sulphide. The filtrate from the copper is slowly boiled till all the hydrogen sulphide is expelled. The uranium is precipitated by ammonia and weighed as oxide. Fre1del And Cumenge separated phosphoric acid from uranium by dissolving the substance in nitric acid, and precipitating the phosphoric acid with ammonium molybdate. The uranium in the filtrate was determined by precipitating it three times with ammonia and weighing as oxide. This method was used f for estimating the amount of phosphoric acid in precipitates of uranous phosphate, which were formed by electrolysis. The sample was dissolved in 30 c.c. nitric acid (sp. gr. 1.42) and 3 c.c. hydrochloric acid (sp. gr. 1.20). When iron was present, the sample was dissolved in a mixture of 20 c.c. hydrochloric acid (sp. gr. 1.20) and IO c.c. nitric acid (sp. gr. 1.42). The solution was diluted to about 100 c.c., and nearly neutralized with ammonia. A few drops of nitric acid were added to clear the solution, making it slightly acid; then to the hot solution (not above 65 0 C.) 50 c.c. of molybdic solution J for every decigram of P205 present. Digested at 65 0 C. for an hour and a half, filtered, and washed the yellow precipitate with cold water. The filtrate was tested for phosphoric acid by adding more molybdic solution and reheating at 650 C. The yellow precipitate of ammoni.
