对硝基苯酚在三乙醇胺改性煤渣的界面行为研究

The Study of the p-Nitrophenols' Boundary at TEA modified Slag/Water Interface

用TEA改性制得了一系列改性煤渣 ,表征了改性煤渣的表面结构特征 ,研究了对硝基苯酚在改性煤渣 /水间的界面行为 ,并探讨了其吸附机理。结果表明 ,用TEA制得的改性煤渣 ,表面羟基含量增加 ,有机碳含量也增加 ,对硝基苯酚在其表面的吸附以形成氢键为主的多层吸附。

By TEA handling, aeries of modified slag has been get. In the paper, the surface composition of the modified slag has been characterized, and the p-nitrophenols boundary at the slag/water interface has been studied. Furthermore, its absorption mechanism has been discussed. The result shows that the organic carbon content of the midified slag'handled by TEA increases with its hydroxy'. The conduct of p-nitrophenols in the slag' surface takes hydrogen bond as the leading factor,and it is a sort of multilayer absorption.
