【摘要】 研究了待测液浓度、温度、搅拌速度以及电极污染、老化等因素对钠离子选择性电极响应时间的影响,进行了相应的实验。实验结果表明,适当增加待测液浓度、温度、搅拌速度可以缩短钠离子选择性电极响应时间;电极的污染、老化会使电极敏感性下降,响应时间延长。更多还原

【Abstract】 Effects of concentration,temperature,stirring speed,electrode contamination and aging of a solution on the response time of the sodium ion selective electrode is studied experimentally.The results indicate that appropriate increase of concentration,temperature and stirring speed can shorten the response time of the sodium ion selective electrode;electrode contamination and aging will decrease the sensitivity of the electrode and prolong the response time.更多还原
