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. |
