【Daily Question】Chemical Engineering Principles 387: Active Silicon in Water (June 17)
Thread Content
This post was last edited by “Back to Cambridge” on June 27, 2016, at 14:13. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, a series of topics such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active participation!!! For the “Question of the Day” activity, answers can be viewed directly in the replies; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What is the purpose of adding acids 1, 2, and 4 when determining active silica in water?
I’m not sure. The company is currently testing and controlling the silica content in the steam condensate, but it still doesn’t meet the standards required for reuse in boilers. I was wondering if the original poster has any information on this topic?
Reduce the silicomolybdenum complex to blue silicomolybdenum blue
Reductant, used to reduce silicomolybdenum yellow to silicomolybdenum blue
To convert silicomolybdenum yellow into silicomolybdenum blue, the purpose of adding 1,2,4 acids when determining active silicon in water is to transform silicomolybdenum yellow into silicomolybdenum blue
