摘要

在微碱性介质中,沉淀剂四苯硼钠(15g/l)使溶液中钾离子析出,产生白色四苯硼钾沉淀,判断溶液中K+含量。以四苯基硼钠为指示剂控制BAF萃取糖蜜酒精废水中的钾。当K+密度低于0.003 (mol/l)时,比色计管底得到的白色粉状沉淀很薄,水中有少量悬浮颗粒。结果对BAF的吸收再生过程有明显的控制作用。

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.
