A new neutral carrier N,N-dioctyl nicotinic amide (DONA) is synthesized for the preparation of polyvinyl chloride membrane pH electrode, the electrode has excellent potential response in low pH range.
本文设计合成了一种在低PH范围对氢离子有很好Nernst响应的新型中性载体——N,N-二辛基菸酰胺(DONA),并把它制成PVC膜PH电极,测试了该电极的线性范围、选择性、稳定性、重现性和内阻等各项性能参数,并试验了电极抗氢氟酸腐蚀的能力,将该电极用于氢氟酸的电离常数测定时获得了满意的结果。
