“…A similar result was observed with nickel. Hasan et al (2007) noted that the exchange of released H þ ions occurs between the surface of the adsorbent and solution resulting in the increase of pH of the solution. It may be noted that the starting pH of the solution was in the range of 2-6.0, and the final pH of the solutions was between 4 and 7 depending on the initial pH.…”

“…Oti et al (2011) used an iron oxide based adsorbent Kemiron for the removal of As(V) and As(III) from leachate. Fuller earth beads and cylinders containing chitosan and sodium silicate as binders was used successfully by Hasan et al (2007) for the removal of cesium from wastewater. This can also be replicated for leachate treatment.…”

Landfills are the primary option for waste disposal all over the world. Most of the landfill sites across the world are old and are not engineered to prevent contamination of the underlying soil and groundwater by the toxic leachate. The pollutants from landfill leachate have accumulative and detrimental effect on the ecology and food chains leading to carcinogenic effects, acute toxicity and genotoxicity among human beings. Management of this highly toxic leachate presents a challenging problem to the regulatory authorities who have set specific regulations regarding maximum limits of contaminants in treated leachate prior to disposal into the environment to ensure minimal environmental impact. There are different stages of leachate management such as monitoring of its formation and flow into the environment, identification of hazards associated with it and its treatment prior to disposal into the environment. This review focuses on: (i) leachate composition, (ii) Plume migration, (iii) Contaminant fate, (iv) Leachate plume monitoring techniques, (v) Risk assessment techniques, Hazard rating methods, mathematical modeling, and (vi) Recent innovations in leachate treatment technologies.However, due to seasonal fluctuations in leachate composition, flow rate and leachate volume, the management approaches cannot be stereotyped. Every scenario is unique and the strategy will vary accordingly. This paper lays out the choices for making an educated guess leading to the best management option.

“…Fuller's earth is a naturally occurring sedimentary clay that consists of silicate, bentonite and a small proportion of magnesium as well as sodium [41]. However, being soft and easily crunching reduces its ability to be used as adsorbent [42]. Hence, it has been combined with other polymeric materials to produce composite materials that can be easily handled and separated within the adsorption process such as the beads prepared by Hasan et al [42,43] from combining fuller's earth with chitosan for use in removing cesium and strontium from waste stream and aqueous solutions, respectively.…”

Kulkarni et al [41] also prepared beads from combining fuller's earth with alginate to be used as an adsorbent for the removal of methylene blue (MB) dye from aqueous solutions.…”

In this study, a highly effective hybrid adsorbent composite based on low-cost fuller’s earth (FE), aluminum silicate (AS) and chitosan (CS) was prepared using a facile method. The prepared composite was applied to adsorb lead (Pb2+) and copper (Cu2+) ions from aqueous solutions. Several analyses such as Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the composite. The adsorption efficiency of the prepared composite was investigated at different operating conditions. Moreover, the adsorption isotherm/kinetic models and adsorption thermodynamics of the composite were examined. The results showed that the pseudo-second-order kinetic model described well with the obtained data and the adsorption equilibrium can be better described by Langmuir isotherm model with maximum adsorption capacities of 305.5 and 284.2 mg/g for Pb2+ and Cu2+, respectively. The obtained data demonstrated that the prepared composite is an efficient and kinetically fast metal ion removal with high adsorption capacity and recovery efficiency. Graphical abstract
