蔬菜废弃物-污泥基活性炭的制备及其正交优化试验
Preparation and orthogonal optimization experiment of sludge-based activated carbon with vegetable wastes
摘要
Abstract
Sludge-based activated carbon was prepared using the mixtures of five different vegetable wastes and municipal sewage sludge respectively.The yield of activated carbon (P),iodine adsorption value (Ivaule) and specific surface (SBET) were used as evaluation indexes.The combination of cabbage-sludge was recognized as the optimized research object.This combination showed the maximum Ivaule and SBEr of 475.19 mg/g and 752.455 m3/g respectivly.Besides,its P was 39.49％.Based on the evaluation indicators of the P,Ivaule and SBEr,the L16(45) orthogonal table was established to determine the optimal preparation parameters as follows:the concentration of ZnCl2 was 2.0 mol/L,the impregnation ratio was 1∶2,the activation time was 0.5 h,and the activation temperature was 500 ℃.Additionally,the results of variance analysis described that the activation temperature had a significant effect on the Ivaule and SBEr of activated carbon.关键词
