AI Technical Summary

Technical Problem

Existing methods for removing palladium complexes from organic solutions are inefficient, particularly for catalysts without phosphorus ligands and those with polydentate ligands, leading to contamination concerns and limited applicability.

Method used

A carbonaceous material with a specific pore structure, characterized by a mesopore ratio of 6.4% to 50.0%, a reactive black pentavalent amount of 1.0 g/L to 8.0 g/L, and an iodine adsorption amount of 1,000 mg/g to 1,600 mg/g, is developed for high adsorption performance of various palladium complexes.

Benefits of technology

The carbonaceous material effectively adsorbs and removes various palladium complexes, including zero-valent and divalent palladium species, from organic solvents, enhancing the removal efficiency and reducing contamination risks.
