| 摘 要： | 本研究通过质子化方法强化壳聚糖的除磷效果,研究壳聚糖的质子化度、吸附时间、磷的存在形态等因素对质子化壳聚糖除磷效果的影响,结果表明,壳聚糖对水中总磷及磷酸根的吸附效果随着其质子化度的升高而呈现明显加强的趋势;质子化壳聚糖对水中总磷的吸附量随着时间的延长而增加,吸附时间在70-80min时达到最大吸附量;水溶液中磷的存在形态,影响质子化壳聚糖的除磷效果。

| Abstract: | This research was focused on the strengthened effect of dephosphorization of protonated chitosan, and studied the influence of protonation degree of chitosan, adsorptive time, existent morphology of Phosphorus and other factors on dephosphorization effect of protonated chitosan. The result indicates that with the increase of protonation degree the adsorption effect of chitosan on total phosphorus and phosphate radical in water was obviously strengthened, and with the extent of time the adsorption quantity of total phosphorus was increased. When adsorptive time was 70-80min, the adsorption quantity reached maximum. The existent morphology of phosphorus in aqueous solution has an influence on dephosphorization effect of protonated chitosan. |
