Strategic selection of an optimal sorbent mixture for in-situ remediation of heavy metal contaminated sediments: Framework and case study

► A framework for in-situ remediation of heavy metal laden sediments is introduced. ► Decision making tools, assessment guidelines and experimental procedures are given. ► Multi-element contamination requires combination of sorbents. ► Pure and waste-derived sorbents are used for optimization of sorbent mixtures. ► A detailed case study demonstrates the efficacy of the framework.
