英文摘要	The color reaction of 2-[2-(4-methylquinolyl)-azo] -5-diethylaminophenol (qadp) with cadmium was studied. in the presence of ph 8. 0 buffer solution and triton x-100 medium, qadp can react with cd2+ to form a stable 2:1 complex (qadp: cd(iii)). the molar absorptivity is 1. 56 x 10(5) l . mol(-1) . cm(-1) at 590 nm. beer's law is obeyed in range of 0. 05 similar to 1. 0 mg/l. the cadmium ion in samples can be enriched and separated by solid phase extraction with anion exchange resin cartridge. this method was applied to the determination of cadmium in water, liver and flour with satisfactory results.
