前言缓冲容量是衡量缓冲溶液缓冲能力大小的尺度,它是缓冲体系最重要的特征之一。自范斯莱克(Van Slyke)提出用数字表达式: (式中:B——缓冲容量,b和a分别代表强碱和强酸的毫克当量数,dPH代表相应于b和a的PH值的变化数)表示以来,已有不少文献和书籍中在讨论和引用它,并称它为微分缓冲容量。 Introduction Buffer capacity is a measure of the buffer solution buffer size, which is one of the most important features of the buffer system. Van Slyke proposes a numerical expression: (where: B - buffer capacity, b and a represent the milliequivalents of strong bases and strong acids, respectively, and dPH represents the change in pH corresponding to b and a Number) has been that many papers and books have been discussed and quoted it, and call it differential buffer capacity.
