高酸度芦苇活性炭的制备及其吸附性能
Preparation and Adsorption Performances of Phragmites australis Activated Carbon with High Acidity
摘要
Abstract
For removal of heavy metals from wastewater and recycling the wetland plants, the present study investigated the viability of using silage of Phragmites australis(PA)to prepare activated carbons(ACs)with high acidity. BET surface area, porous texture and surface functional characteristics of ACs were analyzed by N2 adsorption/desorption, elemental analysis and Boehm titration method. ACs presented well-developed micro-porosity and favorable surface acidity. The sorption equilibrium data for Ni(Ⅱ)and Cd(Ⅱ)sorption onto ACs were analyzed by the Langmuir and Freundlich models. The Langmuir model was fitted well to the adsorption behavior. The properties of high surface acidity promoted the adsorption of heavy metals by the silage-treated ACs and the chemical sorption played the key role in the sorption process.关键词
