壳聚糖改性对高岭土吸附水体氮,磷能力的影响(4600字)
摘 要：氮、磷是引起水体富营养化的主要元素，水体氮磷含量的削减是水体富营养化防治的根本途径。粘土矿物资源丰富，具有特殊的结构组成， 对氮磷有较好的吸附效果。特别是改性的粘土矿物。本论文探讨了壳聚糖改性粘土对水体氮磷的吸附特性。结果表明改性粘土对水中氮磷具有较强的吸附作用，在2h达到基本平衡，并且随着浓度增加效果愈明显。

Adsorptional character of Modified kaolin to nitrogen and phosphorus in water
Abstract：Nitrogen, phosphorus is a cause of the main elements of eutrophication of nitrogen and phosphorus content, and water eutrophication cut is the fundamental way of prevention and control. Clay mineral resources are rich, with special structure composition of nitrogen and phosphorus, has good adsorption effect. Especially modification of clay mineral. This thesis discussed the chitosan modification of clay nitrogen and phosphorus adsorption properties of water. Results show that the modified nitrogen and phosphorus in the water with clay, the strong adsorption role in 2h achieve basic balance, and with the increasing concentration effect is obvious.
Key words：Modified of clay ; nitrogen ; phosphorus; adsorption
