荔枝壳对Cr（VI）的吸附性能研究
ADSORPTION PROPERTIES OF LYCHEE EXOCARP ON CR(VI)
摘要
Abstract
In order to investigate the adsorption properties of lychee exocarp on Cr(VI), the surface characteristics of lychee exocarp was revealed by SEM and the effects of pH, dosage, time and temperature on adsorption were investigated. The results indicated that the surface of lychee exocarp was rough and had strong adsorption ability to Cr(VI). At the temperature of 25℃, the removal efficiency of Cr(VI) reached 91.5% after 3 hours. According to the results of kinetic and thermodynamic studies, the adsorption process was consistent with pseudo-second-order adsorption model and Langmuir isothermal equation.关键词
