- 溶液初始pH值对五氯酚钠的真空紫外光解有很大影响,pH=10.9时的降解速率常数是pH=3.1时的3倍。The degradation rate constant at pH 10.9 was 3 times as that at pH 3.1.Moreover,the apparent first order reaction rate constant linearly decreased with increase of initial PCP-Na concentration.
- 应用摇瓶试验研究了不同初始pH值对白腐真菌Phanerochaete chrysosporium液体培养基在非灭菌环境抑制杂菌效果的影响.Effect of different pH value on suppressing the growth of other bacteria and fungi in culturing Phanerochaete chrysosporium in liquid medium under non-sterile were investigated in agitated Erlenmeyer flasks.
- 以Ti(SO4)2和La(NO3)3为原料,CTAB 为模板剂,从溶液的初始pH值、水热温度、水热时间等方面探讨水热合成条件对La2Ti2O7纳米材料的影响。Layered perovskite La2Ti2O7 naosheets has been synthesized via hydrothermal process from the Ti (SO4)2/La(NO3)3/ CTAB system. The effect of the reaction conditions on the sample has been investigated in detail. The effect of the hydrothermal conditions on the hydrogen production efficiency from photosplitting water has also been studied.
