Instruction Experiment of Study on BAF to Extract Potassium from Molasses Alcohol Wastewater

Among the slightly alkaline mediums, the precipitating agent of sodium tetra phenyl boron(15g/l) precipitates the potassium ion among solutions, produce white potassium tetra phenyl boron precipitate, judge K
⁺
content in solutions. Use sodium tetraphenyl boron as indicator to control BAF to extract potassium from Molasses Alcohol Wastewater. When K
⁺
density is lower than 0.003 (mol/l), the bottom of colorimeter tube to be getting white pulverescent precipitate very thin, a small quantity of suspended particle in water. The result is obviously to control BAF absorbed-regenerated course.
