| 通过A、B和C的红外谱图对比，证明了巯基乙酸参与了反应，从而使巯基成功修饰到壳聚糖纤维素上。考察了溶液pH值在2～7时对WDG吸附性能的影响，当pH<5.0时，吸附率随着pH的增大而增大；当pH≥5.0时，吸附趋于平衡。考察了温度在20℃～60℃时对WDG吸附性能的影响，随着温度的增加，吸附率略有降低。考察了吸附剂量在30～160mg时对WDG吸附性能的影响，随着SBP和TBP质量的增加，吸附率逐渐增大并趋于平缓。随着吸附时间的延长，吸附量增大。在50min时，吸附基本到达平衡。通过对F和G的计算，说明吸附过程是自发进行的，并且温度略低于室温时更易进行。通过巯基改性，有效地增加了竹粉表面官能团的数量，增强了与Cd2+的结合能力，提高了对Cd2+的吸附性能。 |

a rough translation, you need to further modify. Comparison of the IR spectra of A, B and C demonstrates that the mercaptoacetic acid was involved in the reaction, which facilitates the attachment of the mercapto groups on chitosan fiber. The study of the pH dependence of the WDG adsorption properties at the pH rage of 2-7 shows that the adsorption rate increases with the increase of the pH value when pH <5.0 and reaches balance when pH≥5.0. The study of the temperature effect on the WDG adsorption properties in the temperature range from 20C-60C shows that the adsorption rate decreases slightly with the temperature increases. The study of the adsorption doses effect on the WDG adsorption properties shows that the adsorption rate gradually increases and then flattens out. The adsorption volume increases with the elongation of the adsorption time, and the adsorption balance can be reached at adsorption time of 50 min. Calculation on F and G shows that the adsorption process evokes spontaneously, which is more readily proceed when the temperature is slightly lower than the room temperature. Mercapto modification effectively increases the amounts of the functional groups on the surface of the bamboo powder and strengthens the binding capability of Cd2+, which leads to the increased Cd2+ adsorption properties. |
