微波辐照废木屑活性炭制备工艺优化及其应用
Optimization of activated carbons production from waste sawdust via microwave heating and its application
摘要
Abstract
Microwave was used as a heat source in preparing activated carbon (AC) from waste sawdust by Na2CO3 chemical activation in this study. Taguchi method was used to investigate effects of microwave power, microwave radiation time, Na2CO3 solution concentration and solid-to-liquid ratios on iodine value. Results re- vealed that microwave power was the most important factor, followed by radiation time. However, solid-to-liquid ratios had no significant effect. The optimized technological parameters were as follows: microwave power of 440 W, microwave radiation time of 9 rain, Na2 CO3 solution concentration of 15 % and solid-to-liquid ratios of 1:2.5, iodine value was up to 1 230.40 mg/g. Adequacy of model equation for predicting optimal response values was verified effectively by validation. Furthermore, the prepared AC was applied to wastewater treatment, and results showed that, with 3 g/L mass fraction addition of AC, the COD removal rate of wastewater was 77.9% after 70 min adsorption at pH 11.关键词
