摘要:

Cadmium ion reacts with cadion and 1, 10-phenanthroline to form a 1:1:2 orange-red ternary complex in 0.5N sodium hydroxide medium. The complex is extracted by chloroform and has a molar absorptivity of 9.2 × 104l. mole−1. cm−1at 490 nm. A method is developed for the determination of cadmium in electroplating waste water.
