Cryptomelane Modified Biomass Wastes for Solar Interfacial Evaporation and Stabilization of Cadmium

In this work, after carbonization of two biomass wastes, rice husk and coconut husk, they were modified by hydrothermally synthesized cryptomelane manganese prepared into a solar interfacial evaporation system to explore their performance stabilization cadmium. The results demonstrate that the cryptomelane-modified biochar can obtain an rate 1.247 kg m−2 h−1 photothermal conversion efficiency 89.36% under one sun (1 kW m−2). outdoor experiment with average power density only 465.22W m−2, capacity reached 4.7 0.78 within 6 h. cadmium adsorption waste potassium ore increased 50.94%, which could be well used for long-term recycling Cd. It verified material is low-cost, scalable, efficient reduce wastewater pollution. designed in work feasible way clean water solve problems future.
