How to remove harmful heavy metal ions from waste batteries or lithium cells efficiently has been the focus of scholars. More and more metal oxides had been used to deal with the pollution of heavy metal caused by waste batteries in recent years. Nanostructured metal oxides have great potential because of their large comparative areas. The adsorption for these heavy metal ions can be further improved by using modified metal oxides as adsorbents. At present, iron oxide is widely used in this field. Other metal oxides have also been studied in removing these heavy metal ions. Compared to other metal oxides, the adsorbents made of iron oxide are easy to be separated from the reaction system. pH value in the solution can affect the activity of adsorption sites on metal oxides adsorbents and change the distribution of ions in solution. As a result, pH value can significantly influence the adsorption of metal oxides adsorbents for heavy metal ions from waste batteries or lithium cells.

A novel hybrid, water-based, sol-gel method was developed for the synthesis of functionalized silica with advanced adsorptive capacities towards heavy metal ions. The study employs the hyperbranched poly(ethylene imine) (HBPEI) as a reactive template for the synthesis of silica. The reaction was followed by FTIR, whereas the material was evaluated in terms of its microstructure and adsorptive properties. The results revealed a very potent adsorbent that can remove heavy metal ions (namely, Pb, Cu, and Zn) from water in a fast and efficient way. Greater selectivity was observed for lead, whereas the maximum adsorption capacities calculated from the Langmuir model were 833.3, 502.5, and 193.4 mg/g for lead, copper, and zinc, respectively.
