Determination of Nitrophenol in DDNP Wastewater by Cetyltrimethyl Ammonium Bromide Spectrophotometry

Li Qiulian, Ouyang Runqing Ganzhou Non-ferrous Metallurgy Chemical Factory (Jiangxi,341006)  
The chromogenic reaction of cetyltrimethyl ammonium bromide(CTMAB)with 2,4,6-trinitrophenol was studied.Th maximum absorptivity wavelength of complex is at 420 nm, and the apparent molar absorptivity is 1.6×10 4L·mol -1 ·cm -1 .Beer’s law is obeyed in the concentration range of 0~120 g·mL -1 for 2,4,6-trinitrophenol.The method was satisfactory applied to the determination of nitrophenol in DDNP wastewater.
