In order to determine the concentration or supersaturation in crystallization process , an online test apparatus was set up based on the relationship between the concentration and the electroconductivity at a temperature for binary electrolyte systems , which was also used in similar fields to measure the electrolyte concentration 根據(jù)二元電解質(zhì)溶液體系的濃度與電導(dǎo)率和溫度之間的關(guān)系,建立一電導(dǎo)率在線測(cè)量裝置,可在一定范圍內(nèi)測(cè)定溶液的濃度或過飽和度。實(shí)驗(yàn)得到與hlozny等人基本一致的溶液電導(dǎo)率變化趨勢(shì)。
