A comparative evaluation was conducted to evaluate the detoxifying efficiency of different sorbents concerning heavy metals. Metal ion sorption was carried out under static conditions using solutions of CuCl2·2H2O, ZnSO4, PbCl2, and NiCl, all of analytical grade. Lead, nickel, and zinc concentrations were determined through complexometry, while copper concentration was measured by iodometry. To examine the desorption processes, a solution of “artificial” intestinal juice was prepared. The study showed that the half-adsorption time was about 30 minutes and remained constant regardless of the sorbent type. The maximum sorption capacity of the sorbents for heavy metals was determined, and the sorbents were ranked according to their activity. The effect of pH on the specific adsorption values of the sorbents was investigated. In addition, the desorption processes were analyzed under conditions similar to physiological environments, specifically using “artificial” intestinal juice, to investigate the potential for secondary metal intoxication. The findings are useful for selecting the most effective detoxifying agent and optimizing the treatment of heavy metal poisoning.
