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 110°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
