Abstract
A new method (competitive adsorption method) for the removal of Cd from squid liver was proposed. In this method, the same weight of squid liver and citric acid solution were mixed with a cation-chelating resin for 24 h under weak acidic condition. The Cd concentration of the mixture was lowered from 12 ppm to 0.1 ppm by the addition of 10 wt-% of cation-chelating resin relative to the wet-weight of squid liver at about pH 4. The Cd adsorption behaviors of squid liver and cation-chelating resin were well explained by a bidentate binding model. The adsorption process of Cd onto cation-chelating resin was the rate-limiting process of competitive adsorption method.
