摘要
Abstract
A method for determination of ammonia nitrogen in influent and effluent from wastewater treatment plants(WWTP) by ionselective electrode was established,and the measurement conditions were discussed for the concentration of ammonia nitrogen in the range of 0.1 ～ 100 mg/L in water samples.Linear correlation coefficients were between 0.999 8 ～ 1.000,detection limit found was 0.004 mg/L,recoveries found was 96.2％～ 103.8％,relative standard deviations (RSD,n =6) found was 0.57％ ～ 1.62％.Results between the electrode method and Nessler's reagent colorimetric method were contrasted in the analysis.When ammonia nitrogen concentration of the water samples was greater than 0.5 mg/L and less than 0.5 mg/L,relative average deviations found was less than 5 ％ and 10 ％,respectively.The method is simple,without pretreatment and has good accuracy,precision and reproducibility.It,s suitable for the determination of ammonia in a large number of water samples.关键词
