氟离子观测水温干扰因素的排除及实验

Exclusion Experiment of Temperature Disturbances of the Water Sample During Fluoride Observation

由于受观测水温因素干扰,氟离子标准序列的溶液温度和水样水温的温度差值越大,引起氟离子观测误差也越大。通过比测实验,结果表明:恒温和同温氟离子观测方法能消除水温与溶温不同引起的观测误差。得出经验:每日配制氟离子标准序列,选择恒温观测方法;氟离子标准序列不是每天配制,而是批量配制,选择"同温"观测方法。

Due to the observations temperature disturbances of the water sample, the larger the temperature difference of the water sample and the solution of fluorine ion standard array, the greater the fluoride observation error. Based on the comparative temperature, the observation method of the constant temperature and the same temperature can eliminate the observation error caused by two distinct temperatures of the water sample and the solution. If the fluorine ion standard array is compounded every day, the observation method of the constant temperature is choused; otherwise, the observation method of same temperature should be chosen.
