sol-gel method
|
|
Here, after condensation of the pure alumina gel, appropriate amounts of calcium acetylacetonate/water and copper(II) acetylacetonate/ethanol suspensions were added to the aluminium gel. Subsequently, the temperature was reduced to 80 oC and the slurry was heated at reflux for 12 h. 這是采用溶膠凝膠法制備吸收劑文獻(xiàn)中制備流程中的一小段,請問句中提及的“the slurry was heated at reflux for 12 h”是什么意思?在實(shí)際操作中該如何實(shí)現(xiàn)?@崇明先生 |
