So the mixed indicator of phenolphthalein with alizarin red-methyl red could be used as the new indicator for the alkalify water determination. 采用百里酚蓝-甲酚红、溴甲酚绿-甲基红混和指示剂的测试效果较差。
Temperature Two-Degree-of-Freedom Control for Alkalify Process 碱化过程温度二自由度控制
When produce dense sodium carbonate with the material of natural alkali, a plenty of alkaline scrap material or alkaline mud which can alkalify the earth, pollute the air and environment is manufactured, using the scrap material by calcine with a large movable kiln is expensive. 在以天然碱为原料生产重质纯碱时,伴生大量碱性废渣(俗称苛化泥),此废渣堆放或坑埋,碱化土壤,污染环境和空气,若用大型回转窑煅烧处理,成本高不经济。
Study on Indicator Selection for Determination of Water Alkalify 水中碱度测定的研究
Using modified straw to deal with the methylene blue dye solutions, the results show that the alkalify, amination, ultrasonic modification and composite strains of straw adsorbent biological modification processing methylene blue adsorption performance are better than the original solution straw adsorbent. 用改性稻杆吸附亚甲基蓝溶液,结果表明,碱化、氨化、超声波改性和复合菌系生物改性稻杆吸附剂处理亚甲基蓝溶液的吸附性能优于原始稻杆吸附剂。
