改性黄麻纤维协同水泥固化重金属铅污染土的强度及毒理性分析OA北大核心CSTPCD
Strength and toxicological analysis of heavy metal lead contaminated soil solidified by modified jute fiber and cement
改性纤维兼具良好的吸附能力和机械强度,在污染土治理方面具有广泛的应用前景.优选黄麻作为纤维材料,分别采用均苯四甲酸二酐、聚苯胺和双氧水进行改性,结合无侧限抗压强度、土体阳离子交换量(cation exchange capacity,CEC)、电导率(electrical conductivity,EC)、pH值等指标探究改性黄麻纤维协同水泥的固化效能,并借助醋酸缓冲溶液法分析其毒理性演变规律.结果表明,适宜的改性黄麻纤维协同水泥固化铅污染土可同步…查看全部>>
The modified fibers exhibit excellent heavy metal adsorption capacity and mechanical strength,offering broad application potential in the remediation of contaminated soil.Jute was used as a fiber material,which was modified by pyromellitic dianhydride,polyaniline and hydrogen peroxide respectively.The study examined the solidification efficiency of modified jute fiber in conjunction with cement,utilizing indicators such as unconfined compressive strength,cat…查看全部>>
