Benefits of technology

This patented technology allows for effective removal of harmful substances from contaminated waters through chemical reactions between certain metals or compounds (such as copper) and oxidizing agents like H2O2. It also provides methods for producing these complexes without requiring extreme temperatures or pressures during their formation. These properties make it ideal for reuse and disposal after being used once they become depleted over time.

Problems solved by technology

This patented technical issue addressed in this patent relates to developing an effective way to remove harmful metals from industrial effluents without causing environmental damage due to their high content. Current technologies involve expensive processes like filtrations, sedimenting agents, biosolids extraction, and advanced techniques involving solvent absorptions (SAR) or biofilm formation. These conventional ways require significant resources and may cause contamination issues if they were developed too aggressively over time. Nanoporous metal-orgaicate framework materials offer promise because they could potentially replace current synthetic absorbents while maintaining good adhesion properties against certain types of compounds found in industrial effuences.
