橄榄果渣活性炭负载层状双金属氧化物对Cr(Ⅵ)的吸附性能及机制OA北大核心CSTPCD
The performance and mechanism of Cr(Ⅵ)adsorption by layered bimetallic oxide supported on activated carbon of olive pomace
利用橄榄果渣做原材料,通过碱性高温活化法制备橄榄果渣活性炭(OP-AC),采用化学共沉淀法将OP-AC制备为负载层状双金属氢氧化物(FeAl-LDH)的FeAl-LDH@AC复合材料.制备优化结果表明:在Fe-Al摩尔比为2∶1,固液比为1∶15,共沉淀时间为24 h的条件下,制备的FeAl-LDH@AC复合材料对Cr(Ⅵ)的去除效果达到最优.表征结果表明:FeAl-LDH@AC含有丰富的含氧官能团;有大量的Fe元素、Al元素附着到OP-AC表面…查看全部>>
Olive pomace was taken as raw material to prepare olive pomace activated carbon(OP-AC)by the alkaline high-temperature activation method,then FeAl-LDH@AC composite was prepared by loading OP-AC with layered double metal hydroxide(FEAL-LDH)by the chemical coprecipitation method.The results showed that the FeAl-LDH@AC composite with the best removal effect on Cr(Ⅵ)was prepared under the conditions of Fe-Al molar ratio of 2∶1,solid-liquid ratio of 1∶15 and copr…查看全部>>
