摘要：以商品活性炭为原料,采用双氧水、硝酸、氨水、乙二胺四乙酸二钠对其进行改性,研究了改性活性炭对模拟废润滑油的净化性能,探讨了活性炭孔结构及表面化学性质对其净化性能的影响机制;进一步研究了活性炭复配聚氨酯制备碳基滤清器对模拟废润滑油的净化性能。结果表明:氨水(NH_(3)·H_(2)O)和乙二胺四乙酸二钠(EDTA-Na_(2))改性可显著增强活性炭对废润滑油的净化性能,特别是0.03mol/L EDTA-Na_(2)改性,磨损金属元素吸附量和氧化污染物去除率较未改性活性炭提高了28%和97%,且2次再生后净化性能仍高于未改性活性炭。活性炭对废润滑油的净化性能与其微孔、中孔和表面含氮官能团有关,中孔增加有助于有机污染物和磨损金属元素去除,微孔增加有助于有机污染物去除,表面掺杂吡啶氮增强其净化性能。活性炭与聚氨酯经复配、成型、封装制得碳基滤清器,对废润滑油净化效果显著,具有用于废润滑油再生及汽车发动机滤清器的潜力。
The surface modifications of commercial activated carbon with hydrogen peroxide,nitric acid,ammonia and ethylenediaminetetraacetic acid disodium salt were studied.The effects of pore structure and surface chemical properties of activated carbon on the purification performance of simulated waste lubricating oil were investigated.The purification performance of carbon-based oil filter prepared by activated carbon was further studied.The results showed that the modifications of ammonia(NH_(3)·H_(2)O)and ethylenediaminetetraacetic acid disodium salt(EDTA-Na_(2))significantly enhanced the purification performance of activated carbon for simulated waste lubricant,especially of 0.03mol/L EDTA-Na_(2).The adsorption capacities of wear metal elements and organic pollutants increased by 28%and 97%compared with unmodified activated carbon.The purification performance of the modified activated carbon after secondary regeneration was still higher than that of unmodified activated carbon.The purification performance of activated carbon for simulated waste lubricating oil was related to its micropores,mesopores and surface nitrogen functional groups.The mesopores enhanced the removal of organic pollutants and wear metal elements,the micropores was beneficial to the removal of wear metal elements,and the surface doping of pyridine nitrogen increased the adsorption capacity.Carbon-based oil filter which prepared by combining activated carbon with polyurethane,showed the excellent adsorption property and has potential for waste oil regeneration and used as automotive engine filter.
