N,N-二乙基对苯二胺(DPD)-硫酸亚铁铵滴定法测定水中二氧化氯问题的探讨

Discussion on ClO_2 Detection by DPD-Fe(NH_4)_2(SO_4)_2 in Water

对空白试验用水的校对、N,N-二乙基对苯二胺(DPD)的用量、二氧化氯(ClO2)标准样品溶液的稳定性、标准溶液硫酸亚铁铵的滴定速度等因素对二氧化氯测定的影响进行了探讨,提出几点体会,在二氧化氯的测定中有一定的实用性。

Giving discussion about the influence of factors that the proof of water for examination,the dosage of DPD,the stability of ClO2 standard sample solution,the rate of titration of Fe（NH4）2（SO4）2 standard solution on testing ClO2,and giving some opinions,to some extend,which is in a certain practicality on testing ClO2.
