不同量果胶修饰纳米Fe及吸附水中As的研究

Different Amounts of Pectin Modification of Nano-Fe and the Research of Adsorption of As

通过控制加入果胶的量,制备了不同量果胶修饰纳米Fe,并研究了它们吸收水中As(Ⅴ)的容量和速率。结果表明,不同量果胶修饰纳米Fe对吸收水中As(Ⅴ)的容量和速率具有较大的影响,在不同量果胶修饰的纳米Fe中以0.5倍果胶修饰的纳米Fe吸附容量最大,以3倍果胶修饰的纳米Fe吸附速率最大。

The different amounts of pectin modification of nano - Fe were prepared by controlling the pectin amount, and their absorption capacity and rate of water of As（V） were studied. The results showed that different amounts of pectin modified nano - Fe had a great influence on the absorption capacity of the water of As （V） and rate, to 0. 5 times the pec- tin modified nano - Fe adsorption capacity in different amounts of pectin modification of nano - Fe three times pectin modi- fied nanoscale, Fe adsorption rate was the maximum.
