Evaluating the integrated characterization of multiple key molecules could contribute to predicting patients' response to immunotherapy and guiding more effective immunotherapy strategies. A three-compartment photoelectrocatalytic (PEC) cell system combined with ion exchange and chemical precipitation was proposed to recover phosphorus and nickel from electroless nickel plating effluents containing hypophosphite (H2PO2-) and nickel ions (Ni2+). Ion exchange was used to concentrate and separate Ni2+ and H2PO2-. As a key unit, the established PEC system consisted of TiO2/Ni-Sb-SnO2 photoanode and Ti cathode. With 25.8 mM NaH2PO2 and 500 mM NiCl2, 100 % H2PO2- was oxidized to PO43- in the anode cell, 78 % Ni2+ was recovered as metallic Ni in the cathode cell, and 900 mM HCl was obtained in the middle cell within 24 h at 3.0 V. Based on quenching experiments and ESR technique, OH radicals were mainly responsible for H2PO2- oxidation. In situ Raman spectroscopy indicated that Ni2+ initially reacted with OH- to form α-Ni(OH)2, which was gradually reduced to metallic Ni. Fortunately, a slight pH decrease in the cathode cell in the three-compartment cell system was beneficial for Ni2+ reduction to Ni°. The obtained PO43- was recovered by chemical precipitation. Finally, recovery of phosphorus and metallic nickel along with HCl production from an actual electroless nickel plating effluents in terms of efficiency, cost-benefit, and stability assessment were demonstrated. Resin has been widely used for thermosetting printed circuit boards (PCBs) and is a key part of e-waste from scrap PCBs. It requires appropriate treatment because of its harmful elements (metals and metalloids) and organic compounds that are toxic to human health and the environment. The purpose of this study is to eliminate volatile organic compounds (VOCs) and elements (metals and meta
