Uranyl salts react with a-nitroso-jS-naphthol to form a yellow precipitate. It is therefore necessary to take precautions in the presence of uranium, especially when testing for small amounts of cobalt. Uranium may be converted into the non-reacting phosphate by treatment with ammonium phosphate. The test is then carried out as in the presence of iron salts. Limit of Identification 0.26 y cobalt in the presence of 1000 times the Limit of Dilution 1 200,000 ) amount of uranium... 

The results of testing of all of the above materials with standard cultures of bacteria are appended Fig. A4.1, and the accompanying blank Petri dish is for visual inspection of test materials and their identification on the Petri dishes. The antibacterial activity of each material is contained in Table 4.1. Ethylenediaminetetraacetic acid had consistent activity, tributyl phosphate exhibited activity against S. aureus, and the control (chlorhexidine diacetate) performed consistently against all bacteria. 

Identification A 1 20 aqueous solution gives positive tests for Ammonium and for Phosphate, Appendix IIIA. 

Identification A 1 10 solution in l 2hydrochloricacidgives positive tests for Aluminum and for Phosphate, Appendix IIIA, and it responds to the flame test for Sodium, Appendix IIIA. Assay Tetrahydrate Not less than 95.0% Anhydrous Not less than 95.0%. 

Identification A 1 20 aqueous solution gives positive tests for Sodium, for Potassium, and for Phosphate, Appendix IIIA. Assay Not less than 85.0% and not more than 100.5% of Na3K2P3O10. 

Section VIII.4), followed by testing for anions (Sections VIII.5-VIII.7), and by separation and identification of the cations present (Section VIIL8 and VIII.9). Some teachers of qualitative inorganic analysis may prefer to start with the separation of cations - in this case a test for phosphate and fluoride has to be carried out before attempting the separation of Group III cations.
