Abstract

The present invention provides methods for decreasing amounts of metal ions in liquid materials and in porous solid materials surrounded by a liquid, by utilization of sequestering agents that form complexes with said metal ions as well as methods for removing and optionally recovering said metal ions from the complexes. Further, there are provided novel sequestering agents and compositions comprising sequestering agents of the present disclosure.
