【摘要】 在混合碱的测定中,采用自动电位滴定一阶导数曲线法确定滴定终点,与双指示剂法相比,本法具有终点灵敏、误差小等优点,大大提高了测定结果的准确度和精密度.同时也提高了检测的自动化程度,在生产实际中有应用价值。更多还原

【Abstract】 Alkali admixture is determined by automatic electric potential titration and One ank-derivative curve to determine titration terminal point. Compared to double index sign method,the automatic electric potential titration has more advantages: Mensuration terminal point delicacy,smaller error, and so on. Thus the measurement accuracy and precision is consumedly increased as well as the automatization degree of examination, which has applied value in production.更多还原
