摘要: 研究活性白土对染料废水中甲基橙的吸附,考察了接触时间、活性白土的用量、pH值以及温度对吸附作用的影响。获得白土对甲基橙吸附的相关热力学参数,表明活性白土对甲基橙吸附过程是自发进行过程,高温不利于吸附。

Abstract: The adsorption of methyl orange in dye wastewater using activated clay is studied. The effects of contact time,dosage of activated clay,pH value and temperature on the adsorption are investigated.The relaled thermodynamic parrameters of the adsorption of white clay to methyl orange are obtained , indicating that the adsorption process of activated white clay to methyl orange is a spontaneous process,and high temperature is not conducive to adsorption.

Key words: activated clay, methyl orange, adsorption, thermodynamic parameters
