| Abstract: | By use of UV spectrophotometry, the absorption characteristics of mesoporous carbon materials on methylene blue are measured at different time, temperature, concentration, PH value of mesoporous carbon materials on methylene blue in the paper. The results show that the absorption reaches the maximum point when the concentration of methylene blue solution is 5mg/L, temperature 25℃, the adsorption time 8 hours, PH value adsorption 9：00. So it is concluded that the absorption of mesoporous carbon materials on methylene blue is consistent with the two kinetics and in line with the absorotion isotherm of Freundlich. |
