利用水葫芦根系作为生物吸附剂去除水溶液中的Cu2+污染,试验结果表明,在pH5.5,温度为35℃,Cu2+浓度为30 mg/L的条件下,水葫芦根系对Cu2+的最大吸附量可达23.5 mg/g,说明水葫芦根系作为生物吸附剂去除水溶液中的Cu2+是可行的。通过对水葫芦根系比表面积分析、吸附动力学分析、吸附活化能计算、吸附过程离子释放分析解释了水葫芦根系作为生物吸附剂去除水中Cu2+的吸附机理。
利用水葫蘆根繫作為生物吸附劑去除水溶液中的Cu2+汙染,試驗結果錶明,在pH5.5,溫度為35℃,Cu2+濃度為30 mg/L的條件下,水葫蘆根繫對Cu2+的最大吸附量可達23.5 mg/g,說明水葫蘆根繫作為生物吸附劑去除水溶液中的Cu2+是可行的。通過對水葫蘆根繫比錶麵積分析、吸附動力學分析、吸附活化能計算、吸附過程離子釋放分析解釋瞭水葫蘆根繫作為生物吸附劑去除水中Cu2+的吸附機理。

In this study, water hyacinth roots was evaluated as a biosorbent material for the removal of Cu2+ in aqueous media. The data demonstrated the considerable sorption capacity could get to 23.5 mg/g under the conditions of pH5.5, temperature of 55 ~C and CuE+ concentration of 30 mg/L, This confirmed that water hyacinth roots was feasible as a biosorbent material for the removal of Cu〉 in aqueous media. The analysis about SB~, kinetic biosorption, activation energy and ion release in the process revealed the biosorption mechanism of the water hyacinth roots as a biosorbent material for the removal of Cu2+ in aqueous media.
