Shake * 16: United States Environmental Protection Agency (EPA) 16 (naphthalene, acenaphthene rare, acenaphthene, Fluorene, phenanthrene, anthracene, fluoranthene and pyrene, benzo [a] anthracene-and-, benzo [b] fluoranthene, benzo [k] fluoranthene, benzo [a] pyrene, dibenzo [a, , H] anthracene, and INDENE and [1, 2, 3-CD] pyrene, and benzene and [g,h,i] perylene); 17 species: EPA16 species +2 Juan methyl naphthalene; 11 species: Philip, and anthracene, and Fluorene, and pyrene, and benzene and [a,] anthracene, and flexor, and benzene and [e] pyrene, and benzene and [b] fluorescent anthracene, and benzene and [k] fluorescent anthracene, and benzene and [a,] pyrene , Benzo [g,h,i] perylene; 3 species: phenanthrene, pyrene, benzo [a] pyrene6. the 2 shakes of black carbon on the adsorption and desorption of heavy metalCorapcioglu [166] early research on activated carbon for Cu (domain), Pb (domain), Ni (domain) and Zn (domain), adsorption, adsorption process can be considered coordination compounds forming model. Now General think, black carbon adsorption heavy metal of mechanism main has two species, a is black carbon surface adsorption [167], Wu, [168] research has corn straw Rod black carbon on Hg (domain), and As (taro), and Pb (domain) and Cd (domain) of adsorption, found with Langmiur equation intends collection black carbon isothermal adsorption process best, showed that its main is adsorption bit limited of nonlinear surface adsorption, to this way was adsorption of heavy metal very easy solutions sucking, 30 min within wash off rate are in 85% above. Second, functional group on black carbon and electrostatic interactions between heavy metal, including Ion-Exchange [169] and part of the coordination reaction of [170], Qiu, [171] the study think straw straw black carbon and black carbon on Pb (domain), adsorption is the electrostatic interaction mechanisms were relatively stable adsorption of heavy metals. Black carbon, cation exchange capacity (cation exchange capacity, CEC) and its adsorption capacity positive correlation of heavy metals [172], indicates that the 2nd mechanism is the main mechanism of carbon black adsorption of heavy metal. Although Wu [168] the CEC that black carbon in soil/sediment environment than other adsorbents, such as humic acid and clay into small, relatively little of heavy metal ions adsorption capacity, but Liang [173] study on that black carbon by oxidation or other organic matter increase soil adsorption of CEC.土壤中存在的低分子有机酸会影响黑碳对重金属的吸附[174] 。 张文标等[175] 研究了不同炭化温度的竹黑 碳对 Pb( 域) 、Hg( 域) 、Cr( 遇) 和 Cd( 域) 的吸附,结果表明黑碳的比表面积、孔径及 pH 等均影响到吸附重金 属能力,溶液中同时存在的多种重金属离子之间存在着协同和阻碍两方面的效应。6. 3摇 黑碳对营养盐的吸附黑碳可吸附土壤溶液中的 NH+ 鄄N[125,176] 和 NH 鄄N[8] 。 Novak 等[120] 研究认为由于电荷正负性的原因,黑4 3碳对 NH+ N 的吸附能力要强于对 NO- 鄄N 的吸附能力。 添加到土壤中的木炭增加土壤对氮和磷的吸附能力,鄄 3减少了总氮流失量的 11% 和总可溶磷流失量的 69% [177] ,还能增加土壤对钾的吸附能力[123] 。 黑碳可通过间 接方式影响对营养盐的 吸 附, 如 Lee 等[178] 研 究 表 明 氧 化 了 的 黑 碳 表 面 官 能 团 增 多, 可 以 增 加 对 NH+ 鄄N 和NH3 鄄N 的吸附。
