摘要
研究硝酸对勃姆石溶胶澄清度和稳定性的影响,发现随硝酸加入量的增加,超过临界聚沉浓度后,溶胶呈现混浊且性能不稳定.并根据DLVO理论推导出了以硝酸为胶溶剂时其临界聚沉浓度的计算公式,从而对硝酸的加入量可以有一个初步的控制界限.
The influence of HNO3 on the clarity and stability of y -AIOOH gel is analyzed.As a result,we found that the gel becomes turbid and its properties becomes unstable when HNO3 is increasingly added into γ-AIOOH gel till its critical coagulation value.According to the theory of DLVO,the calculable formula of its critical coagulation value by using HNO3 as peptizator is deduced,and then an initial control limit can be given to the amount of added HNO3.
