Investigation into the applicability of Bond Work Index. Oct 15, 2015 The Bond Work Index (BWI or Wi) is defined as the calculated specific energy (kW h/t) applied in reducing material of infinite particle size to 80% passing 100 μm [25]. The higher the value for Wi, the more energy is required to grind a material in a ball mill [10], [26].

Determination of Calcium Ion Concentration
of Ca2+ in a sample may be used with the method for measuring total Ca2+ and Mg2+ concentration using Eriochrome Black T indicator to determine, by difference, the concentration of Mg2+ ions in the sample. Note that this method requires a mol L−1 EDTA solution while the total Ca2+ and Mg2+ method requires a mol L−1 EDTA solution. 6.

In standard two, add 320μl of BSA and 80μl of the 1xPBS solution you created earlier in the lab. In standard three, add 160μl of BSA and 240μl of 1xPBS. In standard four, add 80μl of BSA and 320μl of 1xPBS. Lastly, in standard five, add 40μl of BSA and 360μl of 1xPBS. The next aspect in finding the concentration is to dilute the unknown solution.
