【摘要】 以三辛基十二烷基碘化铵为活性物质，分别以聚氟乙烯（ＰＶＣ）和壳聚糖（ＣＳ）为聚合物支持体，制备了两种铝酸根阴离子选择性膜电极，并研究了它们的基本性能，结果表明，两种膜电极均对铝酸根离子有较好的响应，而ＣＳ膜电极的耐碱性和耐热性优于ＰＶＣ膜电极。更多还原

【Abstract】 Aluminate anion-selective membrane electrode based on hexadecyltrioctylammonium io-dide(HTOA-I)in polyvinyl chloride(PVC)or in chitosan(CS)was made and determined。The results showed that both PVC membrane electrode and CS membrane electrode exhibitedgood Nernst responses for aluminate ion。CS membrane electrode was better than PVC mem-brane electrode at high alkalinity and high temperature。更多还原
