The use of mechanical alloying for the preparation of palladized magnesium bimetallic particles for the remediation of PCBs

► Mechanically alloyed Mg/Pd used for polychlorinated biphenyl dechlorination. ► Initial optimization of Mg/Pd material using a small-scale high-speed ball mill. ► Optimization of four milling parameters for scaled-up ball milling process. ► Pseudo-first order degradation kinetics determined using GC-MS.
