- 溶液初始pH值對五氯酚鈉的真空紫外光解有很大影響,pH=10.9時(shí)的降解速率常數是pH=3.1時(shí)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.
- 應用搖瓶試驗研究了不同初始pH值對白腐真菌Phanerochaete chrysosporium液體培養基在非滅菌環(huán)境抑制雜菌效果的影響.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為原料,CTAB 為模板劑,從溶液的初始pH值、水熱溫度、水熱時(shí)間等方面探討水熱合成條件對La2Ti2O7納米材料的影響。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.
