| Nitric Acid-Insoluble Uranium | 10 to 18 |
| Extractable Organic Material | 19 to 26 |
| Arsenic by Diethyldithiocarbamate (Photometric Method) | 27 to 36 |
| Carbonate by CO2 Gravimetry | 37 to 43 |
| Fluoride by Ion-Selective Electrode | 44 to 51 |
| Halides by Volhard Titration | 52 to 59 |
| Moisture by Loss of Weight at 110176;C | 60 to 66 |
| Phosphorus by Spectrophotometry | 67 to 75 |
| Silicon by Gravimetry | 76 to 82 |
| Thorium by the Thorin (Photometric) Method | 83 to 91 |
| Calcium, Iron, Magnesium, Molybdenum, Titanium, and Vana-dium by Atomic Absorption Spectrophotometry | 92 to 101 |
| Potassium and Sodium by Atomic Absorption Spectrophotometry | 102 to 111 |
| Boron by Spectrophotometry | 112 to 121 |
