| 摘 要： | 阐述了高浓度Cl-水样,以铬酸钾做指示剂,加入适量的硝酸银,形成AgCl沉淀,消除了Cl-的干扰,再用离心沉淀机充分沉淀,取上清液,用COD快速测定仪测定CODcr,有很高的准确度,符合测定要求.

| Abstract: | The detrmination of high concentration Cl-water sample is discussed in the paper.Using K_2 Cr_2 O_7 as indicator,putting proper HgNO_3,Ag Cl is precipitated and Cl-interfernce is eliminated.After that,put the sample in centrfuge to precipitate completely.The clear liqaid is taken.The CODcr determinaton is completed with COD quick detetor.The method is accuracy and up to the standard. |
