The toluene disproportionation and adsorption capacity of aromatic hydrocarbons and water were studied. Hammett indicator method, pulse chromatography and infrared spectroscopy were applied to measure the surface acidity of mordenites. 研究了脱铝丝光沸石的甲苯歧化反应性能及芳烃和水的吸附性能,应用Hammett指示剂法、脉冲色谱法及红外光谱法测定了脱铝后沸石的表面酸性。
The Adsorption Indicator Method to Determine Rapidly Sulfur Trioxide in Salt Cake 吸附指示剂法快速测定芒硝中三氧化硫
The structure of the solid superacid was characterized with acid base titration, TEM, N2 adsorption/ desorption and Hammett indicator. 用酸碱滴定、TEM、N2吸附-脱附和Hammett指示法表征了固体超强酸。
The study shows that Cu's adsorption of cyanotic mud, the same soils produced by the different mother material, is depended on organic matter content of the soil, while the pH indicator will not effect the Cu's adsorption of this type of soil. 对于不同母质发育的相同土壤&青紫泥,研究发现,该类土壤对Cu的吸附与土壤有机质含量呈正相关,而土壤pH对该类土壤对Cu的吸附影响较小;
The acidic concentration of the catalyst was titrated by butylamine with the method of adsorption of coloured indicator. 用吸附指示剂正丁胺滴定法测定了催化剂的酸量。
The adsorption enrichment law of hydrocarbon indicator gases and the relationship between olefin-alkyl ratio and coal temperature can be used to predict the spontaneous combustion of coal. 实验得出的烃类指标气体的吸附浓缩规律,以及气体吸附浓缩后烯烷比与煤温的变化关系等均可以作为煤炭自燃程度的预报指标。
Based on these findings, we constructed a series of surface cluster models to mimic the adsorption and reaction of CH2O," an indicator of MSR mechanism ". 基于MC的结果,我们构建了系列表面团簇模型并考察了作为机理指示剂的甲醛在其上的吸附和化学行为。
