P-mSA/mCS双极膜的制备及其在一价、二价离子分离中的应用
双极膜 磷酸化 二茂铁 一价、二价离子的分离
2009/11/30
以五氧化二磷、磷酸三乙酯和磷酸为反应剂, 制备了磷酸化海藻酸钠(P-SA), 经二茂铁离子改性后作为阳膜层(P-mSA); 用乙酰基二茂铁改性壳聚糖制备了阴膜溶胶(mCS). 将阴膜溶胶流延于阳膜层上, 制备了P-二茂铁-SA/乙酰基二茂铁-CS双极膜(P-mSA/mCS BPM). 测定了双极膜的红外光谱、接触角、电荷密度、离子交换容量与交流阻抗. IR与接触角的分析结果表明, SA经磷酸化后,...

In situ measurements of dimethyl sulphide (DMS) and methane sulphonic acid (MSA) were made at Halley Station, Antarctica (75°35' S, 26°19' W) during February 2004–February 2005 as part of the CHABLIS ...
Ni-mSA-mCS双极膜的制备及其在电合成TGA中的应用
电合成 巯基乙酸 二硫代二乙酸 Ni-mSA-mCS双极膜
2010/1/22
通过用Ca2+改性海藻酸钠(SA)和用戊二醛改性壳聚糖(CS)制备Ni-mSA-mCS(m: modified)双极膜. 镍网预先埋在mSA膜表面作为阴极, 不仅增强了膜的机械性能, 而且降低阴极电解液的IR降, 实现零极距. 测定了膜的红外光谱、电镜扫描、机械性能. 将Ni-mSA-mCS双极膜应用于电还原制备巯基乙酸(TGA). 实验结果表明, 电流密度为10 mA·cm-2, 常温电解, 电...
