Abstract: | In cement production, the speed of clinker analysis is an indicator for the timely grasping of production situations. Use hydrochloric acid (1:1) to dissolve the sample, and determinate Fe2O3 with EDTA titration under the condition of pH=2 and 70℃. After that, add EDTA standard titration solution, and undertake copper sulfate standard solution under the condition of pH=4.3 and 90℃. |
