Abstract: | Objective:The aim was to construct a sample and quick method for the detection of SDS in waste water by UV-vis.Method:Three color agent were used to detect SDS by UV-vis,and quantified by an external standard mode.Result:The SDS showed a good linear relationship with the range of 6~14mg/L with the correlation coefficient R2=0.998. The average recoveries of two waste water were 96.7% and 97.2% respectively,and the relative standard deviation were 5.2% and 2.9% respectively. Conclusion:The detection method was easy to operate,which could satisfy the requirements of the detection of SDS in waste water. |
