“…Attapulgite can eliminate heavy metals from polluted medium (Samara et al, 2019 ). Zotiadis and Argyraki ( 2017 ) reported that the adsorption efficiency of attapulgite was found to be 100% for Cd, 21% for Ba,100% for As, 100% for Pb, 88% for Zn, and 100% for Sb in a primary schoolyard (Otunola & Ololade, 2020 ). For contaminated solutions, Wang et al ( 2020 ) utilized EDTA-modified attapulgite (EDTA-ATP) for the elimination of aqueous Cr(Ш).…”

In the present era of significant industrial development, the presence and dispersal of countless water contaminants in water bodies worldwide have rendered them unsuitable for various forms of life. Recently, the awareness of environmental sustainability for wastewater treatment has increased rapidly in quest of meeting the global water demand. Despite numerous conventional adsorbents on deck, exploring low-cost and efficient adsorbents is interesting. Clays and clays-based geopolymers are intensively used as natural, alternative, and promising adsorbents to meet the goals for combating climate change and providing low carbon, heat, and power. In this narrative work, the present review highlights the persistence of some inorganic/organic water pollutants in aquatic bodies. Moreover, it comprehensively summarizes the advancement in the strategies associated with synthesizing clays and their based geopolymers, characterization techniques, and applications in water treatment. Furthermore, the critical challenges, opportunities, and future prospective regarding the circular economy are additionally outlined. This review expounded on the ongoing research studies for leveraging these eco-friendly materials to address water decontamination. The adsorption mechanisms of clays-based geopolymers are successfully presented. Therefore, the present review is believed to deepen insights into wastewater treatment using clays and clays-based geopolymers as a groundbreaking aspect in accord with the waste-to-wealth concept toward broader sustainable development goals.

“…Recently, attapulgite (ATP) has attracted attention as a soil amendment 14,15 . ATP is a kind of renewable clay mineral with a layer chain transition structure, which is characterized by a large specific surface area and abundant pores 16,17 . Studies have shown that ATP improved soil water retention capacity, promoted soil structure, adsorbed harmful elements in soil, and reduced the activity and harm of soil pollutants 18 .…”

Saline soil reduces soil productivity and exacerbates food security problem. Therefore, it is increasingly necessary to find sustainable farming practices for soil and water conservation. In this regard, conditioning the soil with biochar (BC) or attapulgite (ATP) has been proved as a feasible method of improving water conservation and soil hydraulic characteristics. However, the interactive effect of BC and ATP on saline soil is still unclear. The objective of this study was to investigate the effect of BC and/or ATP on water retention, pore size distribution, hydraulic characteristic parameter, and shrinkage strain of saline soil through laboratory trials. For this purpose, BC and/or ATP were added to the loam soil at three levels of 0%, 2%, and 4% by weight, and saturated in the sodium chloride solution with a concentration of 5 g L À1 . Results showed that the Van Genuchten model accurately fitted the

“…Attapulgite clay mineral has a high specific surface area and high absorption capacity due to the presence of micropores and parallel channels in the structure 16 . Despite the high absorption properties of attapulgite, it did not receive much attention from researchers as a new type of material in the antiseepage liner.…”
