Automatically determining modulus of sodium silicate and its instrument using potentiometry
摘要
Abstract
Method and instrument were introduced which could automatically determine the modulus of the sodium silicates based on potentiometry. The potential signals were collected by signal acquisition unit consisted of the antimony electrode and the temperature sensor.Micro-peristaltic pump was used to liquid fill and titrate solution.The STM32F103 microcontroller was exploited to control the titration process and carry out the data processing.Magnetic heating stirrer was applied to heat and mix the solution.The results show that the method and instrument can determine the modulus of the sodium silicate automatically,fleetly and accurately.关键词
