REMOVAL PERFORMANCE OF Cd2 + USING NANOSCALE ZERO-VALENT IRON EMBEDDED BY β-CYCLODEXTRIN

Kang Haiyan Yang Zhiguang Wan Yuanyuan,

摘要: 为提高纳米Fe0的稳定性,以环氧氯丙烷为交联剂,以β-环糊精为原料对纳米Fe0进行包埋。考察了碱度、交联剂用量对聚合物交联度的影响,对比研究了30%、40%Na OH介质对包埋纳米Fe0去除Cd2+反应活性的影响。利用SEM、TGA对包埋材料的表面形态及热稳定性进行了分析。实验结果表明:40%Na OH介质中交联包埋的纳米Fe0具有更高的反应活性;当Cd2+浓度为100 mg/L时,投加包埋材料3.0 g,反应150 min,Cd2+去除率可达98.9%;于空气中放置1个月,其对Cd2+去除率仍可达90.5%。

Abstract: To improve the stability of nano-Fe0 in the air，embedded nanoscale Fe0 was synthesized using a cross-linked polymer ( β-cyclodextrin and epichlorohydrin) ． Effect of alkalinity，cross-linker dosage on cross-linking degree was evaluated． The encapsulated Fe0 nanoparticles obtained in 40% NaOH medium was compared to that synthesized in 30% NaOH by Cd2 + removal efficiency． The embedded material was characterized with scanning electron microscope ( SEM) and thermogravimetric analysis ( TGA) ． Higher reactivity was observed with the embedded nano-Fe0 synthesized in 40% NaOH medium． A Cd2 + removal rate of 98. 8% ( 100 mg /L) was achieved with 3. 0 g of the encapsulated nano-Fe0 after reacting for 150 min． And the as-prepared nano-Fe0 can still remove 90. 5% of the Cd2 + after being exposed to air for oven 1 month，indicating its excellent ambient air stability．
