| Abstract: | P-Dimethylaminobenzaldehyde was used as developing dye.Spectrophotometer method was used to determine the concentration of sulfamethazine in feed.The limit of detection concentration in this method was 0.05 mg/kg for feed,the average recovery rate of sulfamethazine was 99.2 %,coefficient of variation was less than 5 %.The method had many advantages, such as convenience and speed,less reagent consumption,accurate,higher average recovery rate,little dispersed level etc. |
