Abstract
Sorbent compositions that include a base sorbent material having a high porosity and surface area and a boron-selective agent are particularly useful for the sequestration of boron from waste materials such as coal combustion residual leachate (CCRs). By using a boron-selective agent in conjunction with a high surface area base sorbent material such as activated carbon or biochar, a sorbent composition with a high capacity for sequestering boron at relatively low cost is provided.
