摘要
比较了标准加入法、标准曲线法和硝酸银滴定法对水样测定的适应性,结果表明标准加入法操作简单,测定速度快和重现性好;采用标准加入法对水中氯离子含量进行测定,结果表明,所采集水样中自来水、回用中水、地下水、地表水中氯离子浓度范围分别为24.01~42.97 mg/L、22.37~47.55 mg/L、52.97~59.49 mg/L和12.07~52.97 mg/L。整体来看,所采集水样中氯离子含量未超标,一定程度反映出洛阳市水体水质良好。
The adaptability of the standard addition method,the standard curve method and the silver nitrate titration method for the determination of water samples were compared. The standard addition method was selected and applied to measure the chloride ion concentration in samples due to its simple operation,rapid determination and good repeatability.The experimental results showed that the chloride ion concentration of tap water,reuse water,groundwater and surface water samples was 24. 01 ~ 42. 97 mg/L,22. 37 ~ 47. 55 mg/L,52. 97 ~ 59. 49 mg/L and 12. 07 ~ 52. 97 mg/L,respectively. Overall,the chloride ion contents in all the collected water samples in Luoyang were lower than the environmental quality standards,which reflected the relatively good quality of water to a certain extent.
