| 中文:與單獨(dú)吸附TC不同的是,在酸性條件下協(xié)同吸附的TC吸附量較低,且隨著pH的增加其顯著增加,在pH 6.5時(shí)達(dá)到峰值,隨著pH進(jìn)一步增加至堿性時(shí),吸附量下降。與單獨(dú)吸附Zn2+相比,TC的存在對(duì)Zn2+的吸附影響不大。上述結(jié)果可歸因于水溶液中配合物(TC-Zn2+)的形成或者表面橋聯(lián)(TC-或Zn2+)的作用,在酸性條件下H3O+會(huì)競(jìng)爭(zhēng)吸附位點(diǎn),使吸附不明顯。隨著pH增至6.0,對(duì)吸附的促進(jìn)作用明顯增強(qiáng),Zn2+和TC的吸附量均達(dá)到峰值。pH進(jìn)一步達(dá)到堿性時(shí),Zn2+和TC的親和力減弱,由于其脫質(zhì)子的影響,靜電斥力的作用使TC和Zn2+的吸附量顯著下降[25]。因此,在協(xié)同吸附Zn2+和TC的實(shí)驗(yàn)中,最適pH值為6.0。 |

| Different from the adsorption of TC alone, the adsorption of TC by synergistic adsorption under acidic conditions was low. It increased significantly with the increase of pH, peaked when the pH was 6.5, and decreased when pH further increased to the alkaline range. Compared with the adsorption of Zn2+ alone, the presence of TC has little effect on the adsorption of Zn2+. The above results can be attributed to the formation of complexes (TC-Zn2+) in aqueous solution or the impact of surface bridging (TC- or Zn2+). Under acidic conditions, H3O+ will compete for adsorption sites, so the adsorption is not obvious. As the pH increased to 6.0, the promotion effect of adsorption was significantly enhanced, and the adsorption of Zn2+ and TC peaked. When the pH was further alkaline, the affinity between Zn2+ and TC was weakened. Due to the influence of deprotonation, the electrostatic repulsion significantly reduced the adsorption of TC and Zn2+ [25]. Therefore, in the experiments of synergistic adsorption of Zn2+ and TC, the optimum pH was 6.0. |
