Abstract
In the presence of surfactant sodium dodecyl sulfonate,Fe(Ⅲ) and 3-chloro-N-hydroxy-2,2-dimethylpropanamide can form a stable complex in the acetic acid-sodium acetate buffer solution(pH=3.6) at the maximum absorption of 490nm.Lambert-Beer law was obeyed in the range of 2—160mg·L-1 for 3-chloro-N-hydroxy-2,2-dimethylpropanamide with e490 of1.05×104L·mol-1·cm-1and the linear regression coefficient was 0.9995.This method can be used to determine 3-chloro-N-hydroxy-2,2-dimethylpropanamide in aqueous solution directly,and that is simple and reliable.
