Abstract
Using the microwave method to prepare activated peanut shell charcoal to adsorb Cu2+ . With scaning electron microscope, it was discovered that many thin stripes appeared at the activated charcoal surface, and there were massive pores with average grain diameter of 50μm. In the activated charcoal, the O and C combined and released in the form of CO2, thus caused other elements content to rise relatively, which led the K content to rise most obviously. The adsorptive capacity was the highest when temperature was 30℃, the monolayer adsorption was saturated in 60min and the polymolecular layer adsorption started after 90min. Under the same condition, the activated charcoal adsorption speed and the adsorptive capacity for the highly concentrated Cu2+ solution were more than that of the low concentration solution, and the Cu2+ quantity was more adsorbed obviously in the activated charcoal unit area. Responding speed and the adsorptive capacity were proportional. It showed to be the physical adsorption while the adsorption temperature was between 30 - 50℃, and the adsorption condition transformed to chemical adsorption when the temperature surpassed 60℃.关键词
