Adsorption of heavy metal onto biomass-derived activated carbon: review

Abstract

Physical and chemical properties of carbon are discussed. The keys factors for heavy metal removal are reviewed. Biomass is a suitable material for preparing activated carbon to remove heavy metals.

Recent progress in high-performance environmental impacts of the removal of radionuclides from wastewater based on metal–organic frameworks: a review

“…Meanwhile, the presence of pores on the adsorbent surface causes the enhancement of the adsorption process. 90,91 Organic adsorbents Organic adsorbents are used for various applications such as purication, drying, separation, catalysis, and controlling pollutants. These organic sorbents, such as activated carbon, chitosan, and other organic adsorbents, consist of aromatic sheets condensed over each other, forming a hydrophobic character.…”

Adsorption of Organic Pollutants on Carbonaceous Adsorbents Prepared by Direct Activation of Sweet Cherry Stones

“…Unfortunately, the vast majority of them concern the removal of one type of pollutant, e. g. dyes, VOCx, heavy metal ions or toxic gases. [24][25][26][27][28] Articles devoted to the adsorption of pollutants of various chemical nature (that very often occur simultaneously in wastewater) are still rare.…”

Removal of heavy metals from binary and multicomponent adsorption systems using various adsorbents – a systematic review

“…Previously, several review articles have been published and most of these studies are based on the removal of heavy metals from single component adsorption systems by using various adsorbents as well as applying conventional isotherm and kinetic models to explain their mechanisms of adsorption. 2,[31][32][33][34][35] Only a very few reviews focus on heavy metals removal in multicomponent systems and the application of multicomponent adsorption isotherm models in describing sorption mechanisms. [36][37][38] Undoubtedly, broad reviews are useful in comprehending the adsorption of different water pollutants such as heavy metals, dyes, phenols, and pharmaceuticals in multicomponent systems.…”
