The present review comprises various novel foam adsorbents with unique adsorption performance inprocess of removal of dyes and heavy metals. Water pollution because of toxic dyes and heavy metalsand its ill-effect on the ecosystem is of great concern to researchers, as it affects the living creatures onthe planet. Novel foam adsorbents from carbon foam, chitosan foam, metal foam and polymer foamwere developed as efficient materials with good chelating ability to adsorb dyes and heavy metal ions.Novel carbon foam adsorbents were reported to have superior adsorption capacity in removal of dyesand heavy metals. This review aims to look at various novel foam adsorbents used in adsorptionstudies and their potential in dyes and heavy metals removal. This work provides a worthy challengeand the future possibility for designing novel foam materials for various applications.
