In HCI media,Bi（Ⅲ） was reacted with I^- to form ion complex[BiI4]^-,which further associate with norfloxaein （NRF） to form the association complex,resulting in the new resonance Rayleigh seat-tering （RRS） is significantly enhanced and the maximum RRS wavelength is loeated at 469 nm. Under the optimum condition ,the linear ranges and the detection limits are 3.2—130μg/L and 0.96μg/L,respectively. This method is simple, sensitive. The NRF in milk samples were analyz...
