摘　　要：结合BET、FTIR,考察了投加量、时间、AMO浓度、温度、pH值和离子浓度等因素对吸附的影响。结果表明,YKC对AMO的去除效果受投加量、时间、AMO浓度、温度和p H值的变化影响较大,在投加量为30 mg,AMO浓度为100 mg/L,温度298 K,时间为4 h的条件下,YKC对AMO的吸附量和吸附率分别达到了88.67 mg/g和53.67%。pH值和FTIR分析表明,静电吸引和氢键作用是YKC吸附AMO主要机理。The effects of dosage,time,AMO concentration,temperature,p H value and ion concentration on adsorption were investigated by combining BET and FTIR.The results showed that the removal effect of AMO on YKC was greatly affected by the change of dosage,time,AMO concentration,temperature and p H value.Under the conditions of dosage of 30 mg,AMO concentration of 100 mg/L,temperature of 298 K,and time of 4 h,the adsorption capacity and adsorption rate of AMO on YKC reached 88.67 mg/g and 53.67%,respectively.The analysis of p H value and FTIR spectra showed that electrostatic attraction and hydrogen bonding were the main mechanisms of AMO adsorption on YKC.
