WebApr 11, 2024 · The limits set by EN 12953-10 are in a similar range of <0.03 to <0.0 ppm of copper in feed water and less than 0.1 ppm copper in make-up water. Voltammetry is a sensitive method for the determination of metals such as copper or iron. WebReliable water content values for these soils can be obtained by drying in an oven at approximately 60 to 80°C. The percent of water content shall be calculated as follows: w = (W 2-W 3) (W 3-W 1) × 100. Where, w is Water Content Percent; W 1 is mass of container (bowl) in gram; W 2 is mass of container (bowl) with wet soil in gram
