Therefore, the green glass adsorbent can be used to treat wastewater containing heavy metal ions with a concentration ranging from sub-ppm to %. The glass structure is retained on purpose during the transformation process, so the green glass adsorbent can work with acids and chemicals and can even be used to treat wastewater in a low pH medium (equating to 0) to accomplish effective absorbing goals.
