生物炭与非常规碳质改良剂对土壤-植物系统中有毒金属(胶体)的作用机理研究
发布时间:2021-06-10 19:31
近几十年来,随着采矿业和工业的不断发展,各种人类活动引起的土壤中重金属含量的日益增加,严重危害了土壤环境。这些被污染的土壤具有糟糕的物理和化学性质,一些重金属在土壤中长期存在,而这些重金属很难被化学和生物降解,从而阻碍了植物的生长。目前已经研发了多种物理、化学和生物修复技术,这些技术有助于降低农业土壤、工业复合污染土壤和铜尾矿中重金属的危害。其中有种修复技术是利用高表面区域的有机或无机吸附剂进行原位固化,根据土壤或铜尾矿的物理化学结构以及释放到环境中重金属的量,降低金属阳离子的生物利用度和迁移率。使用不同有机和无机改良剂进行的金属固定化被认为是一种低成本的管理实践,是一种环境友好型的方法。它主要通过沉淀、吸附和复杂的形成处理,利用各种化学和生物反应成功地固定金属离子。本研究中以竹炭为原料,加入非传统的含碳改良剂,如粉煤灰、煤矸石、烟煤和褐煤,作为矿山污染土壤和铜尾矿重金属的固定化剂,对铬、钴、镍、铜、锌、镉、铅等重金属进行了原位分析。此外,在使用生物炭之前,对煤矸石和烟煤进行水热处理,对粉煤灰进行酸洗和水热处理。根据实验设计,这些改良剂将被单独使用,或者按照1%-2%的比例与生物炭结合...
