| 通過A、B和C的紅外譜圖對比，證明了巰基乙酸參與了反應，從而使巰基成功修飾到殼聚糖纖維素上�？疾炝巳芤簆H值在2～7時對WDG吸附性能的影響，當pH<5.0時，吸附率隨著pH的增大而增大；當pH≥5.0時，吸附趨于平衡�？疾炝藴囟仍�20℃～60℃時對WDG吸附性能的影響，隨著溫度的增加，吸附率略有降低。考察了吸附劑量在30～160mg時對WDG吸附性能的影響，隨著SBP和TBP質(zhì)量的增加，吸附率逐漸增大并趨于平緩。隨著吸附時間的延長，吸附量增大。在50min時，吸附基本到達平衡。通過對F和G的計算，說明吸附過程是自發(fā)進行的，并且溫度略低于室溫時更易進行。通過巰基改性，有效地增加了竹粉表面官能團的數(shù)量，增強了與Cd2+的結合能力，提高了對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. |
