| Abstract: | The coupling reaction condition of 8-Hydroxyquinoline with NO-2+--Sulphanilamide diazotium salt and their polarographic behavior was studied.Linear relationship between secondary derivative wave height and concentration of NO-2+- can be obtained in the range of 0.002~0.2mg/l.The method has been applied to determing NO-2+- in environmental water with the recovery of 98~103%. |
