利用电导率检验牛奶掺假丁伟，杨百亮，黄素珍，赵良璧，张维保牛奶各种成分的含量是相对稳定的，它们以不同的形式存在于乳中，其乳糖和无机盐分别以分子、离子形式溶解于乳中，由于其含量变化很小，形成的自由离子恒定，因此牛奶具有一定的导电性￣［１］，电阻的范围在... Detection of Milk Adulteration Using Conductivity DING Wei, YANG Bailiang, HUANG Suzhen, ZHAO Liangbi, ZHANG Weibao Milk contents are relatively stable. They exist in different forms in milk, and their lactose and inorganic salts dissolve in molecular and ionic forms, respectively In milk, due to its small content changes, the formation of free ions constant, so the milk has a certain conductivity ~ [1], the resistance in the range of ...
