The tracer must be a gamma-ray emitter, must be compatible with the flowing liquid, and must have a half-life longer than the duration of the test. Tracers generally used are salts of cesium-134, iodine-131, sodium 24, "or gold-198. There are two methods of flow measurements by the radioactive tracers: 1) Two-Point Method and 2) Total-Count Method.
· 5. ASTM Method D859-16, silica, colorimetric, manual. In this method, soluble silica in the sample is reacted with molybdate then reduced to form a blue complex in solution. The intensity of the blue complex is determined with a spectrophotometer or filter photometer and the concentration of silica is determined by comparison with a standard curve.
