A research group in the United States has developed a process to recover lead in its metallic form so that it can be reused in the PV industry. The process relies on a leaching solution based on a combination of acetic acid (CH3COOH) and hydrogen peroxide (H2O2), which the researchers said leaches the lead 'in a matter of minutes.'Scientists at Arizona State University have developed a new two-step process to recycle lead (Pb) in photovoltaic modules at the end of their life cycle. "No recyclers talk about lead recovery because it does not generate much revenue but adds to the cost of recycling," ...Den vollständigen Artikel lesen ...
