摘要
目的 ]测定极弱二元碱的含量 .[方法 ]在二元碱的CbKb2 <10 - 9,Kb1/Kb2 为 10～ 2 0 0倍的情况下 ,通过推导分析结果的误差ΔVe2 /Ve2 与ΔpH之间的关系 .[结果 ]在CbKb2 ≥ 0 85× 10 - 12 的条件下 ,分析结果的误差ΔVe2 /Ve2 均小于 1 0 % .
OBJECTIVETo determine the content of exc eedingly weak alkalies.METHODSIn the case of C bK b2 < 1 0 -9 and 10<K b1 /K b2 <200,through inferring the relation bet we en analytical results error ΔVe 2/Ve 2 and ΔpH, the content of exceedingly w eak diabasic alkalies could be determined by using contrast method. R ESULTS The analytical result errors ΔVe 2/Ve 2 were all less than 1 0% when C bK b2 is more than 0 85×10 -12 , and the method was s imple and realiable.
