Facile Ball-Milling Synthesis of CuO/Biochar

2.1. Optimal Ball-Milling Parameters and Comparison of Adsorbents. Because CuO was the modification agent of the nanocomposites, the ball-milling conditions were opti-mized based on the sorption capacity of CuO to RR120. CuO powder were ball milled under different combinations of ball-milling time, speed, and agate ball-to-CuO mass ratio. The
