“…Hydrophobic and π-π interactions have been recognized as an additional mechanism controlling the adsorption of MCs onto adsorbents [20,135,157,158]. Hydrophobic interactions are a result of the tendency of molecules to adsorb onto a carbon surface instead of remaining dissolved in water [130].…”

“…The results showed that the dominant adsorption mechanism was electrostatic interactions for both FTL and PIC. These interactions were weaker due to the lower negative charge of FTL caused by the smaller amount of acidic functional groups; therefore, the overall adsorption efficiency was lower [20].…”

“…According to the literature, adsorption has been widely studied, and is considered one of the most attractive treatment alternatives for removing pollutants from water [17] including dissolved extracellular MCs from water sources. Adsorption exhibits significant advantages over conventional methods, including technical, economic, and environmental considerations [18], and it can be applied on an as-needed basis, since CyanoHAB problems are transient and intermittent in nature [19,20]. Activated carbon (AC) is among the commonly used adsorbents for effective MC removal, due to its porous nature and large specific surface area [18].…”

The increasing occurrence of toxic cyanobacteria in water sources, driven by climate change and eutrophication, is of great concern worldwide today. Cyanobacterial blooms can negatively affect water bodies and generate harmful secondary metabolites, namely microcystins (MCs), which significantly impair water quality. Various adsorbents used for MC removal from water sources were assessed in this investigation. Activated carbon constitutes the most widely used adsorbent for treating contaminated waters due to its high affinity for adsorbing MCs. Alternative adsorbents have also been proposed and reported to provide higher efficiency, but the studies carried out so far in this regard are still insufficient. The mechanisms implicated in MC adsorption upon different adsorbents should be further detailed for a better optimization of the adsorption process. Certainly, adsorbent characteristics, water pH and temperature are the main factors influencing the adsorption of MCs. In this context, optimization studies must be performed considering the effectiveness, economic aspects associated with each adsorbent. This review provides guidelines for more practical field applications of the adsorption in the treatment of waters actually contaminated with MCs.
