Abstract
The invention relates to a method for separating metals present in a solution using chitosane. According to the present invention, chitosane in modified physical form is used which allows faster, more extensive fixation of the metals present in a solution. This purpose is achieved using a method in which the chitosane used is a lyophilizate of chitosane, in particular a lyophilizate of chitosane salt. ##STR1##
