不同改性活性炭吸附苯酚和亚甲基蓝的实验研究
Experimental Study of Absorption of Phenol and Methylene Blue with Different Modified Activated Carbons
摘要
Abstract
In this paper, activated carbons prepared from wood, shell, coconut shell and coal were selected and modified by nitric acid and sodium hydroxide for determination of the one with best removal efficiency of phenol and methylene blue. Simultaneously, study of the optimal dosage, pH value and adsorption time was also conducted. The results showed that the adsorption effect of alkali modified wooden activated carbon was the best with larger specific surface area and developed porosity. The optimal dosages for the phenol and methylene blue solutions with initial concentration of 1g/L were 1.5 g and 0.5 g respectively. When the value of pH was below 10, the alkali modified wooden activated carbon had higher removal rate of phenol, but the pH value had little influence on methylene blue removal. The adsorption effects were better in strong acid, neutral and alkaline solutions. The alkali modified wooden activated carbon had high adsorption rate of phenol, with the removal rate reaching to 88% within a rather short time. After 20 minutes, the adsorption of methylene blue by the alkali modified wooden activated carbon tended to balance with the removal rate of 90%.关键词
