食用菌菌渣转化的多孔碳作为一种高性能吸附剂去除水中双酚A的研究

s one of the Endocrine-disrupting chemicals, bisphenol A (BPA) can impersonate the natural hormones and disturb .metabolic processes of human body. As environmental problems become more severe, BPA is detected even in drinking water. Adsorption by activated carbon is an important way to remove organic pollutants from water. In this work, theporous carbon material with the specific surface area of 3878.2 m3g-1 was obtained by the carbonization and activation processes. Preparation process is facile and easy to operate, and the chemical reagents used in whole process are only potassium hydroxide and hydrochloric acid, which achieves the green enviromental protection. These porous carbon materialsexhibited excellent performance for absorbing BPA in water. The adsorption kinetics showed that the adsorption behavior was in accordance with the pseudo-second-order kinetic model.The adsorption performance of these porous carbon in the acidic and neutral conditions is outstading, and the maximum quantity can reachas high as 1249 mg/g, whereasthat in alkaline conditions decreased significantly. The adsorption model of the process was also explored and demonstrated that the adsorption process was well consistent with the langmiur adsorption model.
