“…Adsorption is one of better technologies for water and wastewater treatment due to its low cost, high efficiency, and easy handling (Bavi et al, 2023;Filho et al 2023;Scanlon et al, 2023;Waghmare et al, 2023;Yang et al, 2023). A number of studies were carried out on zirconium-based adsorbents.…”

The studies on materials for decontamination in aqueous solutions have increasingly received greater attentions. Such contaminants as heavy metals, arsenic, fluoride and phosphate are harmful to humans and aqueous species due to higher toxicity. Zirconium based adsorbents have become more attractive due to outstanding performance in decontamination. This article provides a comprehensive review of the performance and mechanisms of five types adsorbents: zirconium (hydro)oxides, zirconium hydrogen sulfate, zirconium based multiple metal typed adsorbents and zirconium impregnated complexes. The pseudo-first order and pseudo-second order equations and the intraparticle diffusion model can be applied in describing the adsorption kinetics, while Langmuir and Freundlich equations are the most commonly used adsorption isotherms. The important mechanisms for uptake of contaminants are: ligand exchange between adsorbate and adsorbent, surface complexation formation, and Lewis acid–base and electrostatic interactions. A series of successful studies demonstrate that the adsorbents are promising for removing aqueous contaminants.

The current studies deal with the use of low-cost orange peels as an adsorbent for the removal of methylene blue from aqueous solution in the batch adsorption experiment in the laboratory. The adsorption of methylene blue dye on an orange peel was examined on the basis of different parameters such as dye concentration, quantity of adsorbent, particle size of orange peel, pH, and contact time between adsorbent and adsorbate. Also, effects of these parameters on adsorption were studied. The adsorption was favorable for acidic pH. Maximum adsorption takes place at pH 6. Also, the removal efficiency increases with adsorbent dosage. Adsorbent dosage of 0.5 g shows considerable dye removal. Dye color removal rate increases with increase in contact time between adsorbent and adsorbate. The Langmuir model fits better to the adsorption equilibrium data. The adsorption capacity of orange peel is quite low. Orange peel can be used as a substitute for expensive adsorbent as it is a cheap and bio adsorbent.
