摘要
利用自动电位滴定仪分别测定了NaClO2固体质量浓度为20mg/L,10mg/L,5mg/L,2.5mg/L,1mg/L和NaClO3(与盐酸反应)质量浓度为20mg/L,10mg/L,5mg/L,2.5mg/L,1mg/L的水样,分别求出其回收率及检出限。试验表明电位滴定法能在5mg/L以上质量浓度快速准确的区分测定ClO2,Cl2,ClO2-和ClO3-。
The solid sodium chlorite contents of 20,10,5,2.5 ,1 mg/L and the sodium chlorate (reacted with hydrochloric acid) contents of 20,10,5,2.5,1 mg/L in water samples are determined respectively by autopotentiometric titrator. The recovery rates and detection limits are figured out, respectively. All these show that the potentiometric titrimetry can determine chlorine dioxide, chlorine, chlorite and chlorate at more than 5 mg/L in water quickly and accurately.
