Removal of toxic metal ions from wastewater is crucial for the clean environment, aquatic
life, and human health. Among several removal techniques, metal ion coordination induced
gelation of low molecular weight organic ligand (gelators) and subsequent separation of the
metal ions from gelators is a newer technique in this field. In the last decade, several gelator
molecules have been developed for the sensing and removal of toxic metal ions from
wastewater and may find potential application on the above purpose. This review article …
