| Abstract: | Objective To establish methods for quantitative determination of diquat in water samples. Methods Ultraviolet spectrophotometry and second derivative spectrometry methods were developed and validated to analyze the diquat residues in water samples. Results For ultraviolet spectrophotometry and second derivative spectrometry methods,the calibration graphs were linear in the ranges of 0. 1 ~ 50 μg / mL and 0. 1 ~ 10 μg / mL,the relative standard deviation values for both intraday and interday precision were less than 2. 6% and 1. 29%,respectively. Conclusion Two methods studied were rapid,simple,sensitive and suitable for the environmental monitoring. |
