“…With the advancement of technology and the research on the spiritual and health benefits of jade, the large amounts of waste produced in the process of jade mining are gradually becoming a concern [2]. Researchers are striving to modify and reuse various solid wastes to optimize environmental resources [3][4][5][6], and such research is in high demand globally [7][8][9][10]. This study focused on the jade waste from the Xiuyan area, Liaoning province.…”

The Xiuyan jade waste exhibits prominent antibacterial properties after mechanical activation; these properties can be further optimized through low-temperature annealing. To elucidate its antibacterial mechanism, analysis methods involving metal-ion leaching monitoring and zeta potential analysis were used. Although the activated waste cannot be easily dissolved in water, Mg2+ and Ca2+ ions precipitated when the waste particles were dispersed in water. The particle surface showed different degrees of electronegativity, which could be the main reason for the antibacterial properties of the material. This study proved the importance of the surface electrical properties of activated waste particles on their properties by observing their adsorption capacity for methylene blue. At the annealing temperature of 270 °C, the Xiuyan jade waste exhibited the highest electronegativity and optimal antibacterial properties as well as the adsorption rate of methylene blue, verifying the significance of electronegativity of activated mineral waste powders on the antibacterial mechanism.
