摘要
以河南某地膨润土为原料,用硫酸对其活化,详细研究了活化过程中固液比、硫酸浓度、反应时间及反应温度对活性白土质量的影响,成功地制备出脱色力大于200、活性度超过国家化工行业标准规定的各类一等品标准的高效活性白土。
Sulphuric acid is used as the activation reagent. reacting time and temperature are studied in processing clay The solid-liquid ratios, Sulfuric acid concentration, ore with bentonite from Henan. The activated degree of the product is increased by processing bentonite ore. The activated clay with high quality is prepared successfully.
