摘要
[目的]探讨测定极弱二元酸含量的简便方法.[方法]用对照法测定极弱二元酸邻苯三酚及间苯二酚的含量.[结果]在CKa1<10-9,Ka1/Ka2>270倍的情况下,用强碱滴定极弱二元酸可获得满意的结果.[结论]对照法是极弱二元酸含量测定的有效方法.
OBJECTIVE To study simple and rapid assaying of exceedingly week acids. METHODS The contents of Pyrogallol and Resorcinol were detected by contrast method. RESULTS The satisfactory results could be obtained in the case of CKa1 〈 10^-9, Ka1/Ka2 〉270. CONCLUSION The contrast method is effective method in assaying of exceedingly week acids
